Definition of druid?

The cyborg crypt-keeper who you never actually fight, but who's included in a cutscene when you first try to enter the secret passageway and completely wipes your entire party.

EDIT: Erp. One of a destroyed Mage village's best sorceror's; is disguised as a common healer to slip past guards. Heals the protagonist after a cutscene in which the party is swept into the sea and split up; disappears just as the protag is waking up and visits you while you're taking a break at an inn, then joins your party.
