On a whim, the witch Lima Ray helped the goblins being persecuted by the elves and ended the elf nuisance for them. After that, the goblins worshiped her as a living god.
Lima Ray's powerful magic worked in tandem with the goblins who served as her transportation, and they went around the world causing all kinds of mayhem.
The goblins would love to return to those glory days. Thus, they have been conspiring to bring her back from the dead with a spell she had taught them. However, without Lima Ray, It's a simple matter to crush their ambitions. You easily staved off her attempted resurrection.
The goblins seem to resemble the player characters.
