Nerissa

Nerissa is a human woman in her mid-20’s. She has dark hair,
green eyes, and brown skin. 
Her real name is
Mesika. She is a warrior of Mezro who is investigating the happenings in Chult, particularly the machinations of the dark forces operating in the midst of the Death Curse. Only a chosen few know her true identity, which she does not reveal under any circumstances until the end of the adventure. 
Nerissa is proud and honorable, but despises dark magic almost to a fault. She goes through great lengths and puts herself in grave danger to eradicate any trace of necromancy and dark magics tied to the dead.
