Stories
7Character details
An assassin disguised with a skull mask.
One of the successive Hassan-i Sabbah who served as "The Old Man of the Mountain," the leader of a group of assassins. While alive she was known as "Hassan of the Serenity" for her mastery of poisoning.
Profile 1
Height/Weight: 161cm, 42kg
Origin: History
Region: Middle East
Alignment: Lawful-Evil
Sub-Attribute: Human
Gender: Female
Her face during infiltration missions is created through her transformation skill to disguise herself, but her third Ascension form is her natural looks. Due to the nature of her assassination methods, she has a true face.
Profile 2
The assassins took the concept of a "Poison Damsel," a story told in ancient India, and brought it to fruition in a form of assassination tool. That is the nature of her existence.
Profile 3
Her beauty is but an illusion. Her body is immune to all sorts of poisons yet is the collection of all poisons. Her nails, her skin and even her body fluids are toxic, and she has silenced many kings and generals in their bedrooms.
Profile 4
She would fall in love or be betrothed to someone only for the purpose of assassination. In other words, she continued to create an illusion of happiness, just to take it away with her own hands.
Eventually, her mind broke.
Profile 5
Perhaps she met her end when a certain general took her head out of suspicion that she would not let him touch even her hands. Perhaps she revealed her identity as an assassin and begged the general to kill her.
Or perhaps, she was killed by someone when the general was not paying attention.
Additional profile
All that matters to her is whether those she touches live, or die.
So if her Master possesses a strong resistance to poison, that would be quite the sight for her to see. Try though she might to contain herself, she would grow excited and follow her Master around, leaning on them.
