Stories
7Character details
This woman from first-century Rome was a poisoner in service to the Caesars. She was discovered by Nero's mother Agrippina and is said to have supplied the poison used in the murder of Claudius, the fourth emperor of Rome. She then served the newly crowned Emperor Nero and was involved in the assassination of Nero's half-brother, Britannicus. Locusta is further believed to have been involved in several other assassinations of important figures.
She is the archetypal poisoner in Western nations. The nineteenth-century author Alexandre Dumas père, who penned "The Count of Monte Cristo," frequently compared the character of the poisoner in his novel with Locusta.

Origin: History
Region: Rome
Alignment: Chaotic-Balanced

Gender: Female
Have some delicious mushrooms!
Profile 2
A weirdo with too much energy. She has a bizarre obsession with mushrooms. She idolizes Nero and is also friendly to Nero's allies. While she often gets carried away with herself, she is at least cheery and fun to be around. However, she's got more than a few screws loose. As a consequence, she tends to give out poison entirely without malice.
Be wary of her.
Profile 3
Poison Mixing: A+
The ability to concoct poisons infused with magical energy. Poisons created with this skill cannot be detoxified without the intervention of Mystics. This skill works similarly to Item Construction.
Cooking (Mushroom): B
A technique of cooking ingredients to make delicious dishes. Locusta especially excels at the preparation of mushroom dishes. This skill is derived from her legend of sprinkling poison on a dish, making this one of the ways Locusta applies her poisons.
Profile 4
『Finis, Fungus』
Rank: C+
NP Type: Anti-Personnel/Anti-Army
Range: 1 - 5
Maximum Targets: 1/7
Mushrooms, Be They a Sacred Food Offering.
Hot stewed mushrooms are forcefully served to the target by pouring the mushrooms over them. Obviously, the stew is laced with poison. This attack does not inflict Death, as Locusta is unable to use poison potent enough to kill without Nero's orders.
Profile 5
『Finis, Venenum Nero』
Rank: EX
NP Type: Suicidal
Range: -
Maximum Targets: 1 (*Effective only on Nero)
Farewell, My Beloved Emperor.
The finest poison kept within a small golden box. Locusta put her heart and soul into the making of this poison. It sends the imbiber to their final rest, quietly extinguishing the flame of their life. It was said Nero took this box with her when she fled to the garden in Servilius, but died by her own blade and never had the chance to take the poison inside.
...This drove Locusta mad.
Additional profile
May the great Emperor Nero die in peace. This is Locusta's goal. However, having been consumed by madness, Locusta doesn't realize that that is not her true wish. If only there had been some miracle that led Nero to overcome death... If only Nero had met someone who could have worked such a miracle... Then, and only then, could Locusta open her heart to another.
That's right: Locusta truly wanted that beautiful girl to have lived. Just...lived. She truly wished for Nero to have just lived.
"Well either way, I'm still going to use my poison. That's not going to change."

- Hehehe, Master. I've got my hands on some quality mushrooms. These are some really high quality, irresistibly scrumptious...matsutake mushrooms.
- Bond Level 3
- Nero's adoptive father Claudius passed away from eating poisonous mushrooms. Yes, that's how the story goes. And then Nero...well, Nero got so fond of mushroom dishes that they were deemed to be the food of the gods. That is certainly an honor beyond my wildest dreams.
- Bond Level 4
- In the beginning, I made it for Lady Agrippina...and then I served Nero. My poison was for Nero...only for Nero. Ah... So then why!? Why did you meet such a pitiful demise instead!? That tiny box was a crystallization of my life's work! It was supposed to have been poison just for you!!!
- Bond Level 5
- To distance oneself from the palace filled with blood, poison, and conspiracy...to go far beyond that falling sun... Master, if your journey leads to a place like that and you can take my beloved Nero along, I will offer you all I am and can do. And right now, I will serve as your poison, Master.
