Profile
Ch'en, head of the Lungmen Guard Department's Special Inspection Unit, graduated from the Royal Victorian Guard School with superb grades and outstanding achievements. During her time with the Department, she cracked down on crime, fought violent offenders, tracked down armed fugitives, and brought down international criminals.
Now works at Rhodes Island, providing on-site tactical command.
Clinical Analysis
[At the request of the Lungmen Guard Department, this information will not be made public.]
She did come in for a physical examination, but her files have been confiscated. I have no way to get them. Why? I was told not to.

[Originium Arts Overview]
Ch'en has never been seen using Originium Arts, which led many to suspect she didn't have a talent for it. Indeed, she did struggle to control her abilities, blasting the occasional hole in a wall, blowing files everywhere, and causing more collateral damage than might otherwise be acceptable. Using Originium Arts for too long tires her out. After discussion with the tech staff, it was decided Ch'en lacked the necessary conduit to control her Arts. Without one, Ch'en could never master it.
I saw her test results. The thinner the staff, the better she is at assimilation. But what's the point? Maybe if you had something shaped like a sword, it might work for her. But who would want to use it for that? A sword is for slashing! We're going to need a lot more work on this..

Ch'en graduated from the Royal Victorian Guard School with straight A's in all mandatory subjects and glowing recommendations from her professors. After returning to Lungmen, she almost immediately joined the Guard Department.
No one knows anything about her life prior to enrolling in the L.G.D. School, and no one questions her ability, dedication, or hatred of her enemies. Police officers working with Ch'en often complained about her demeanor--too strict and too harsh. Everyone thought that this harsh character would disappear in the struggle for power, and she would soften up after being worn down by endless incidents.
Surprisingly, both crime and casualty rates have declined in the past two years, and the younger generation of officers began being promoted faster and more substantively. Ch'en was promoted and joined one of the most important teams in the Department, the Special Inspection Unit.
Members of this unit are generally not allowed to serve more than two years - to protect their lives and reduce their stress. Perhaps this position isn't suitable to serve for a long time: old inspectors' careers always seem to end with heroic sacrifice.
Ch'en did not retreat. She doesn't even know how to back down.
She became the fastest promoted officer in the history of the Lungmen police force, and also the youngest Special Inspector in the Department. Those who ridiculed her were impressed by her perseverance. After all, planning for the future is one thing. Planning every day is another.
Why was she so hard? Why live life this way? No one can could understand.
There are often small pieces of paper that have been ripped apart or angrily crumbled in Ch'en's trash bin.

Of course, Ch'en is not a total workaholic.
Officers who know her say she is almost perfect. She operates efficiently, scheduling her time wisely such that she can exercise and tend to her hobbies. Every minute of her day is filled with meaningful activities.
And yet this worries her colleagues even more. It is common for her to cancel her days off and to work overtime on into the night. It's also common for a mountain of paperwork to disappear one day only for her to get called into an urgent meeting when she is about to go see a movie.
She is mechanically efficient. People naturally ask her,
'Are you stressed?'
'No reason to be.'
No one has ever gotten a different answer out of her.
Ch'en lives this way every day, always doing what she can for Lungmen and honing her skills. She is always getting better, and the sky is the limit.
But what exactly is she pursuing?
Even her friends wouldn't say they understand Ch'en. She tries to do it all.

[Classified Log]
'Your father has cut ties with you. He doesn't have anything to do with me, either, but neither of us care.
Do you want to leave?
You can, but I have something to tell you before you go.
I actually know who that old person is.
But I forget a lot of things -- like that night you and your friend had a little adventure. It's easy to forget.
It's my fault. I made an unforgivable mistake.
I will forget.
If you want to leave, I will send you to a city that is safe, rich, and stable. You would have a peaceful life there.
And you will say goodbye to everything here. The home you hate, the street you hate, the people you don't like.
It's just that you will lose your opportunity to know the truth. The facts are dangerous, and I can't have innocent people getting involved.
Angry? You're angry with me? You hate me?
Well, of course. Let me be who you hate. Hate a powerless person like me.
Here is your other choice.
You choose to stay.
From now on, I would train you. You would be free to hate me and even try to kill me, if you want.
How could you not? Of course you can. You would be a natural.
Your body and mind both belong to you. I can teach you right from wrong, and if you do well, you should work with Originium on your own.
Don't forget it, just do it.
Being able to do things right is worth the hard work. Having to fix a mistake could be fatal.
Even I don't know what is in store for us in the city. It is full of opportunity. Anything can happen.
It doesn't matter if you don't understand now, you will later.
Hey, I still remember. I remember that last thing you said.
Do you persist, or do you give up?
Choose.'

Module record
7th of July, clear. On her birthday, she was excited to show Wei Yenwu the unsheathing, but couldn't find a trace of him anywhere. After three days, she waited no longer.
13th of May, cloudy. She cut down a thirty-year-old tree in the courtyard with Tearrender, smashing the roof in. Wei Yenwu did not appear, and merely sent someone to plant a new tree. She never hoped for Wei Yenwu's acknowledgement again.
1st of January, heavy rain. On a New Year's visit, in the downpour, she saw an injustice on her way to the slums, struck out in anger, and took fifteen on her own. In this moment of mortality, she fled into the night by her hilted sword, harming seven, repulsing eight. When she landed atop, Wei Yenwu made a rare appearance, saw the sword marks, and gave her a single look before leaving. She's forgotten why she struck out at the time, but will never forget the disappointment in that look.
25th of December, clear. Acted in bravery while heading home from the Royal Guard Academy, totally fearless, slashing grand and bold, sparing as called for. She was high on spirit, believed she could hew away all injustice in the land.
30th of July, cloudy. At the cost of five days unconscious, let out Shadowless, ultimately cutting down a major fugitive. Lungmen's Ch'en Hui-chieh, shining in prominence. After waking up, Chi Xiao was placed by her bedside, and Wei Yenwu hadn't once come to visit her.
13th of August, overcast. Midway pursuing an Infected criminal, was eager to strike out with Chi Xiao. Chi Xiao did not budge one hair. Subsequently, in this moment of mortality, inspiration struck, Chi Xiao was unsheathed, and cut half a subterranean garage down. She sought Wei Yenwu to find out why Chi Xiao had and hadn't, but Wei Yenwu did not meet her.
30th of September, clear. Chi Xiao was unsheathed a second time, cut open a treasury door, and saved the hostages within. She began to understand, Chi Xiao was a sword of will. She thought she had always done more than enough, but had in actuality done too little. She had to be faster, and mightier.
7th of July, cloudy. On her birthday, over a decade coming, Wei Yenwu asked for the first time to see her swordplay. She condensed all she'd learned, and made an incomplete Cloudsplitter her final examination's answer. Wei Yenwu did not comment.
1st of January, clear. Left Lungmen together with Rhodes Island. From here on forth, Chi Xiao will rarely be unsheathed.

Module record
The scars on the earth came blitzing in from the horizon, striking true at the Victorian-style complex. The buildings are like a forest torn apart by a whirlwind, collapsed in a radius surrounding a singular point. In these ruins of the Empire, two figures turn over a toppled stele, attempting to find higher ground.
'How long has this place been empty?' Ch'en stands atop the rubble and looks into the distance. The names on the stele behind her once stood for glory, now all but worn away.
Bagpipe's voice comes from somewhere below. 'This school buildin's been abandoned since the war broke out. All the students who didn't complete their course yet got sent off to new campuses, finished the rest out there... Chenchen, that's our old trainin' grounds up in front. You remember?'
'Especially well. I feel like my time as a student was defined by missing out on things. The moment I graduated, they finished repairing the roads, and the training grounds.'
The training grounds have been blown by the shockwave into a plate of jagged protrusions. Ch'en picks up a stone, flings it into a shrub sticking out of a crack in the plate, and a fowlbeast hiding within flies off for somewhere far away, screeching and cawing all the while.
'Things were good enough as is, back then.' Bagpipe's voice comes in close as she stops and stands by Ch'en's ear.
'True. It was probably the simplest time of my life. I didn't have all these issues weighing on my mind, I just had to focus purely on training and studying.'
'That's what drove you? You trained like a maniac every day, got As on every standard subject and all.' Bagpipe clasps her hands on Ch'en's shoulders, and gently rocks back and forth.
'After I returned, I realized just how many things couldn't be solved with swords. There were times I felt far too insignificant, and that even though I worked hard, I couldn't change all that much, sometimes, taking out the enemy doesn't do a thing to address the problem.' Ch'en shakes her head, as if trying to throw her tangled mess of feelings about the past straight out of her brain.
The two of them head up a steep slope. The flowerbed is still where they remember it.
Half of the logo of the once-eminent Royal Guard Academy is submerged in the mud, the other half resting against a fractured stone pillar. Sunset spills across, the light pouring over the symbol now mottled with rust, and what remaining metallic shine there is speaks to the place's former glory.
'It's all changed. Victoria's changed too, hasn't it?' Ch'en mumbles to herself, staring at the crest.
'Some people haven't changed. I went to go visit Instructor Tyrell a few days ago 'cause I knew you were comin'. You were gone in such a hurry back then, you just left all your papers and stuff in the dorms, she's been keepin' them safe all these years. All this is proof of you passin' your studies. Oh, aye, and this too!'
Bagpipe fishes out a stack of documents from her bag, as well as a wooden sword.
'Here's the trainin' sword you used back then. Was meant to go back, technically speakin', but you did so smashin' the instructors were goin' to give you it, y'know, as a surprise for you...'
'Give her my thanks. I left too quickly...'
'At least you've come back now. So many of our year never have, even after all this time.'
The two fall silent.
'Where do you think you'll be in ten years?'
'Who knows? We should be heading back soon. There's still a lot to do.' Ch'en gazes into the distance, off in the direction of Lungmen. 'They arranged everything for me, whether it was going to this school or leaving it. Now, I'm going to go back by myself.'
