Bane

A goblin god of war, worshipped by Droghen and those who work under him. According to Talxa, Droghen enforces this worship and the goblins under his command are not free to worship the other goblin gods, such as those that her altar has statues of.

So that the party can cooperate with Droghen's underlings, he gives them his symbol of Bane to show them, which Grokko carries.
