King Grol

The Goblinoid leader of the Goblins in Cragmaw Castle. He kidnapped Gundren and was with the elusive Black Spider. However King Grol decided he wanted to back out of his agreement, and the Black Spider sent a Doppleganger to knock him out, tie him up and leave him in the closet.

When the party killed the Grol Doppleganger, and found him tied up in the closet, they decided to let him live. Darien wanted to commit regicide via trial by combat, but was outvoted.

Droop had no nice things to say about Grol from his time in the Cragmaw Kitchens, and Klarg didn't seem particularly loyal to him either.
