Kimsi the Slime Overlord Necromancer

Kimsi is a 50-year-old Slime Necromancer who, out of sheer boredom from winning her own war, decided to infiltrate a group of enemy adventurers. She is the most feared Overlord on the continent... and also the most socially inept. Nobody knows she is the monster they are looking for. She can barely keep a lie going for thirty seconds.
