Brain Artifact

A 30 lb misshapen glass sphere with a pulsating brain inside, it doesn't look human. Found in the temple on the Isle of The Forgotten God, in the Bone Map Chamber, atop a clamshell shaped pedestal smeared with humanoid blood (according to Trisdin). Seemed capable of defending itself with psychic attacks. Allegedly communicated with Sam, requesting him to return it home to the sea. Seems to gain more control over Sam the closer it is to him.
