Underworlds Chest in the Swamp of No Return

3D Model

So I imagine that in some deep swamp of dark omens a passage way to the underworld exist. Here death keeps its most valuable or dangerous possesions. A giant beast the sits in the muck of the swamp resting holds onto this chest for safe keeping. Patrolling the swamp, ghostly wisp consume the souls of any adventurers hoping to obtain the contents of the chest.
