Crucible is a Warforged Artificer who is employed at the Red Hammer, a Warforged Bar located in the Cogs. She waited on the PCs on their first trip to the Red Hammer and her friendly nature quickly ingratiated her with the members of the group.
Book especially found a kindred soul in Crucible, as both are Warforged “females” whom have skill in the Arcane magics. Crucible has offered to assist Book with any future modification, something Book intends to take Crucible up on in the future.
Crucible introduced the group to Blue.
