The Folly of the Gods
It's innocence when it charms us, ignorance when it doesn't.
Splug is a goblin the Bizarre Force found locked up in the ruins of Shadowfell Keep. Not much is known about Splug, other than the fact that the rest of the goblins hated him, especially Balgron, who had him locked up.
Splug traveled with the Force briefly, but disappeared during the fight against Sir Keegan. He later appeared during the undead seige on Winterhaven to kill Ninaran and save the day. He has again disappared shortly after.
Splug once again showed up in the Horned Hold under Thunderspire Mountain, where he used a mixture of Douven's potions to cure the Bizarre Force of their polymorph curse. He has disappeared again, but his reappearance seems inevitable.
