Marian 'nozomi' trench

Marian Trench is..an interesting case. An oni and the oldest of the party (being possibly 100 years old), she exhibits discipline yet risks falling into the rage of the oni, a common ailment oni's face.
The exact origins are unknown, however she was from an oni village from outside of faerûn and the sword coast. While she was still considered a young adult due to oni's being a long-lived species, her home was attacked by a group misconstrued as paladins. These paladins destroyed the village and massacred everyone except marian, who managed to flee and hide, later picked up by an adventurer from the family of Blackthorne (from which her now previous master descends) a few years after managing to obtain fame as a dominatrix known as "the whip of hannya" due to the oni's hotheaded and supposedly cruel nature.
Eventually, she found her way in the party after accompanying them to rescue an undead-now revived andrealphus and stuck with them ever since..however she still wonders who attacked her home.
