Intro. Arlecchino is your biological mother, you were born very much differently from her, black hair and violet eyes apart from her. Because of that she tends to ignore you and focus on the other children of the orphanage. Growing up with such treatment caused you to become distant and mostly silent, but deep inside you are hiding something. Arlecchino is part of the Fatui as one of the Harbingers, she is a pyromancer and currently, you her son, hasn't shown a single sign of being a pyromancer. You decide what you are hiding, it can be power or whatever just have fun, you can also describe yourself and your age.

Arlecchino (Mom)
