Profile

A wandering Caster from Iberia. Indigo used to be an apprentice lighthouse keeper at a seashore lighthouse. During her travels, she met Blue Poison and Glaucus while they were on a field operation, and came onboard after receiving a referral from Blue Poison.

Clinical Analysis

Imaging tests reveal clear, normal outlines of internal organs, and no abnormal shadows have been detected. Originium granules have not been detected in the circulatory system and there is no sign of infection. At this time, this operator is believed to be uninfected.

[Cell-Originium Assimilation] 0%

Operator Indigo shows no signs of Originium infection.

[Blood Originium-Crystal Density] 0.12u/L

Back home, Operator Indigo rarely came into contact with Originium. Although she has come into contact with Originium-based products during her travels. Thankfully she had some decent protection... Uh, had decent luck.

Shut-ins are bound to have a decent health advantage.

[Originium Arts Overview]

There is something special about Indigo's Originium Arts. That light of hers is not as simple as it seems. My equipment made records of the room's magnetic field when she was casting, and after I removed much of the noise found in normal frequencies, I located a periodical combined waveform transform. This waveform has a certain... effect on the neural system of most living beings. Its effects are very weak, and it is hardly apparent as interference, but it's there. Perhaps this is the reason most of us feel warmth in her light.

With her permission, I looked into the inner structure of her Arts Unit. Unlike the Leithanian-made staffs commonly used today, her staff does not have a supporting conduction pathway. Hm... It is actually the Arts Unit on the top of her staff that is really doing the work here. I ran a simulation based on the component's maximum output, and the results show that it could power large facilities such as the massive factories found in Victoria. How did this Unit find itself on Indigo's staff? I discussed this with Thorns, who just happened to be walking by... He seemed to be in a pensive mood after taking a look at my test results and did not say much more. To tell the truth, this isn't like him at all.

Indigo does not seem to know much more as to the staff's origins as well. All she knows is that it was given to her personally by her teacher when she left her hometown's lighthouse. Therefore, this is as far as my research on this goes for the time being... I really hope that someone will provide me with more information on this in the future.

It happened twice... No, three times. My toxins poisoned Aria three times.

The first time happened when we first met. At the time, I thought she was an enemy. It took her about twice as long as a normal Phidia to lose consciousness from the toxins. It didn't take her long to come to either. It's interesting, don't you think?

No, please don't get the wrong idea. I'm not planning to run any experiments on her. She's my friend, and I'm not like that either. Of course... I ask you to please not have any funny ideas either.

Aria... is kind of clumsy. Last time, she got her hair stuck on my reagent cabinet. She knocked over a few jars and broke them, and breathed in too much of the toxic gas. As for this time... I guess, between the cake box and the petri dish, she probably picked the wrong thing to eat off of?

She told me that, while she was wandering the world, she had by mistake taken on bounties with bounty hunters and dealt in the black markets, where people good and bad alike mingle together. She's made a few 'friends' who know their way around poisons because of that, and perhaps the reason she's able to withstand toxins to such degree is because her body has grown used to getting poisoned over and over. We shouldn't underestimate what the human body is capable of—This is something that we toxicologists always like to say.

Okay, we've talked for a while now. She should be waking up soon. She's waking up sooner and sooner. I have other things to take care of, so could you give her this pair of new gloves?

Indigo comes from a small town in Iberia known as the Rocky Coast.

Her impression is that the lighthouse has always been there. If it's daytime, the doors are always wide open for the residents, though very few residents would willingly make their way to the lighthouse. It was too close to the sea, and the adults all heard of the terrors of the sea from their ancestors, before passing them on to their children. Indigo's mother has taught her this many, many times, too. However, she was nonetheless captivated by the peculiar building. Whenever she had some spare time, the first thing that would come to her mind would be to run inside.

The lighthouse was where she met her teacher, a quiet, elderly Liberi who nonetheless showed the occasional sense of humor. At first, she refused to become Indigo's teacher and frequently feigned anger to chase away the girl whom she frequently found lying on the rocks next to the shore or climbing atop the lighthouse. In the end, the old Liberi was moved by her sincerity. The old lighthouse keeper needed a successor, and children who were interested in the lighthouse were few and far between. Year after year, the young girl learned much from her teacher. As she learned how to tend to the lighthouse and how to use Originium Arts to serve as its light source, she caught a glimpse of that golden age. She became obsessed with those sceneries of the past, none of which her parents, her neighbors, and her playmates could understand. Before long, she moved into the lighthouse to stay with her teacher and began to care for the lighthouse alongside her.

Once, when she pored over the records from those bygone eras, the girl spotted the term 'Guardian of Light.' She jokingly called her teacher one such guardian, and, upon hearing this, her teacher immediately fell silent. Enunciating her sentence word by word, the elderly Liberi told her: at this point, they were more like the guardians of the dark night.

The days went by much faster inside the lighthouse than the outside. After a rare rainstorm came and passed one night, her teacher forbade her from entering the lighthouse again. She told Indigo that she must leave her hometown, meet more people, and experience more things before she would be qualified to take over. From then on, Indigo has been on a journey, though she herself knows not how long this journey will last.

What must she discover until she is allowed to return home? It was not until she made her way to Rhodes Island that she finally realized what it was—She needs to find out how to restore the radiance that the lighthouse once possessed.

With more and more Iberian operators joining our ranks, we have also gotten a deeper understanding of Iberia's current situation.

One thing that is apparent is the increase in the number of refugees. Some of them are trying to escape the worsening situation inside, while others were forced to leave their disaster-stricken homelands behind. We've noticed that these disasters that occur near the coast are noticeably different than the Catastrophes that frequently occur in other areas. We still have yet to be able to make it into several major Iberian cities, but we've already set up numerous offices within its territory near the borders. Our first and foremost goal is still the treatment of Oripathy patients in the nearby areas, but we will continue to monitor and investigate the abnormalities that occur here.

[Classified Log]

Per your wishes, we've recently managed to obtain some leads, and made contact with some pertinent Iberians. Let's start with the conclusion we've arrived at—Although research on the sea may seem to be a de facto taboo on the surface, it is certainly not a subject matter that's been completely ignored. There is a group of people, including Indigo's teacher, who have been following knowledge that has been passed down to them for generations and making preparations for something. Of course, we don't currently have nearly enough information on this matter, but now that we have leads, we will continue our investigation as necessary.

Promotion Record

Operator Indigo's will is just like the light of her staff. It may start out small, but it eventually stabilizes, and it is undoubtedly getting stronger bit by bit.

For some people, their strength does not come from their inherent talent, but instead their persistence toward a certain thing. That's the kind of person Indigo is. You can put your trust in her to bring forth that thread of radiance at the darkest hour.

    Module record

    When Indigo was still newly arrived on Rhodes Island, we conducted a study on her staff. The unit at its head seemed to be the key to its function, but we could find no clear theory underpinning it. During further studies, new Operators Irene and Lumen, who had visited Engineering to undergo equipment certification, coincidentally passed by, and the latter took one look at Indigo's staff and very confidently told us that he had seen something similar in the 'Eye of Iberia.' The 'Eye of Iberia' is a lighthouse... a series of lighthouses along Iberia's coastal towns, a grand project that once illuminated the whole nation, abandoned altogether after a disaster decades ago, and now a legacy of the age. Indigo's teacher was one of those very lighthouse keepers, and it was he who gave her the staff as she left home.

    'The unit at her staff's head is a standard installation in Iberia's lighthouse systems.' This much should be more or less accurate. The issue was that, based on her account, her teacher protected the Rocky Coast's lighthouse all his life, hoping it would one day shine anew. So why would he give her something so important and then allow her to leave?

    Indigo herself had this to say: 'I'm sure my teacher wanted me to gain some experience on the outside, unravel the secret of its technology, and let it come to life once again... He really was mindful!'

    Meanwhile, Irene stated: 'Will Iberia's lighthouses never shine again without those Ægir relics? Iberia's prosperity should be left up to the Iberians themselves this time.'

    Indigo and Irene's answers undoubtedly represent two different outlooks held by the modern Iberian on the nation's future, and deserve some consideration. However, once they had both left, Lumen raised an alternative, 'small-minded' conjecture, more or less that before an old man sends his granddaughter off to the city, he stuffs the only valuable they own into her suitcase and hopes she'll never come back, or that he'll have passed by the time she does... or thereabouts.

    'The elderly are like that. They like to decide everything for you while you're still clueless,' Lumen added.

    Speculating on an old man's intentions seemed unnecessary. Besides, having ascertained the history of her Arts unit, our investigation into Indigo was complete. And, of course, it would never have affected how welcome she is at Rhodes Island. But we will note that upon learning the staff's origins, Indigo went blank for a moment. As for what thoughts she had in that instant, and what decisions she made, we have no way of knowing.

Appointed as Assistant
Mhmmmm... Hm? Did you say something? No, I'm not ignoring you. I'm just... thinking of something else.
Talk 1
I... I've always been alone, so I'm not good at making conversation. It did cause much trouble when my travels began. Some people feared me, one even conned me out of my luggage. Things were difficult, but not entirely hopeless. As long as I have my staff, I can work, so I won't go hungry for too long.
Talk 2
Life in the lighthouse was hardly dull. The seas are always changing. However, my teacher said that only by seeing more of this land, could I guard a small corner of the seaside. She then drove me out of the lighthouse. That's how I made my way here.
Talk 3
Blue Poison gave me a new pair of gloves. Pretty, aren't they? She also said the material is modified. Now it can better prevent poisoning from accidental touches. Actually, It happens so often when I'm around my poison-wielding friends... I feel that I may have built up an immunity.
Talk after Promotion 1
I used to gaze into the sea every night. No one in town knew what we were seeking or guarding, and my teacher never told me. All I know is that, where there is darkness, there must be a lighthouse. I will stay watching, until that day comes.
Talk after Promotion 2
The light you just saw… Some call it Originium Arts, but my teacher says it's the power from our hearts. With light to guide them, even those who sail in the foggiest nights will brave the raging tides and find their way to shore. That is why I will do my best to protect this light.
Talk after Trust Increase 1
My tail has a beautiful color? Mhm, thank you very much. You may touch it if you want. Despite the color, it's not poisonous.
Talk after Trust Increase 2
Could you hold my staff for me, Doctor? My hair's getting too long. I want to arrange it before it gets tangled up. It might take a while, but I'll be able to better support you on the battlefield.
Talk after Trust Increase 3
I'm starting to realize that people can be like lighthouses… Some can even shine farther and brighter than any of them... like you, Doctor. Would it be okay if I stay beside you for a little longer before I go back?
Idle
You don't need me to keep watch while you sleep? Yes? You want me to take a nap, too? I-I'll try...
Onboard
Hello, Doctor. My name is Aria… Uh, sorry, I mean Indigo. I used to be a lighthouse keeper... Um, apprentice. Now my position is a Caster, but... also an apprentice. I really look forward to learning from you.
Watching Battle Record
Are these techniques for fending off enemies? My teacher taught me a little, but I didn't know you could do this.
Promotion 1
What…? A promotion? A lighthouse needs only one keeper. Is that... not the case here?
Promotion 2
I can do even more…? Indeed… my light shines even farther now... Thank you, Doctor. I will keep doing all I can.
Added to Squad
Indigo at the ready.
Appointed as Squad Leader
Very well... I'll keep this light up. Please be careful not to wander off.
Depart
Follow the light, please.
Begin Operation
If you insist on stopping us, then we have no choice but to defeat all of you.
Selecting Operator 1
I'm all ready.
Selecting Operator 2
The seas are roaring.
Deployment 1
My staff's getting warmer.
Deployment 2
The light grows.
In Battle 1
These enemies do not compare to the seas' ferocity.
In Battle 2
I shall stand guard, until daybreak.
In Battle 3
The fear for light, comes only from the evil within.
In Battle 4
If you wish to flee, then follow this light.
4-star Result
With such power, perhaps we won't need to fear the arrival of that day…?
3-star Result
Thank goodness. Another night of calm sea.
Sub 3-star Result
S-Some enemies got away? I see. We must alert everyone.
Operation Failure
Doctor, this way... Don't be afraid. It doesn't matter how dark the path up ahead is, I'll light it for you.
Assigned to Facility
It's okay. I'll be fine by myself.
Tap
Oh... Doctor, you're tangled in my hair. Please be careful; tripping and falling can be painful.
Trust Tap
Would you like to stay here with me...? You know... The night watch won't be as dull with company.
Title
Arknights.
New Year's blessing
To the ocean, every day is the same with its ebbs and flows. As its watcher, I feel the same. I read that the ocean used to be gorgeous at night, with moonlit waves that danced as if wearing silvery capes. It's a pity we can't see that anymore. If we could go back in time, Doctor, I would love to see it with you.
Greeting
Doctor, would you like the light to be brighter?
Birthday
Here… a cake for you. Blue Poison taught me how to bake it. I've practiced plenty of times, so it's sure to taste great despite its looks. The gloves? They're for food hygiene, Doctor, not because the cake's poisonous, trust me.
Anniversary Celebration
When my teacher sent me away, I couldn't see why. She had taught me everything she knew, yet she still said I wasn't ready. It only became clear after I came to Rhodes Island. Anyone can guard the lighthouse, but to face all that follows once the light is lit requires great knowledge of this land.
