Wants and Needs is part of the monster slayer team I dubbed The Caravan. Due to them needing to maintain some sort of cover, W&N had to remove their mask when all the monster slayers went to the Ebroseme Empire to kill the emperor. W&N's real name is Ladislas Schoorl, and although they're male, by modern standards we'd consider them non-binary, though they're less the "I reject my assigned gender at birth" and more the "I'm not even a person" type of NB. Their main goal is to kill all life, and this was even admitted by W&N's party members to the player characters, though ultimately they consider W&N harmless.
