Grodd goblin

Grodd goblins were a sub-race of goblins that were trapped in the Grodd demiplane with Nalavarauthatoryl.

Due to the demiplane's close proximity to the Plane of Shadow, the Grodd goblins developed abilities that allowed them to not be harmed by the touch of shadows.

Grodd goblins spoke a corrupt form of "Ancient Elven".
