Tales of Tolgard
The Greff are a band of gnolls. They were involved with the necromancer Sedric Blightning some years ago with an evil plot of his. They were based out of a stronghold named the Greff Stronghold. When the Avengers came to the stronghold, they turned the surviving Greff against Sedric Blightning. The Greff then helped lead the assault on Sedric Blightning’s crypt complex.
Recently it was learned that part of the Greff band for a while were living in the Ruins of Tolgard but moved on after their numbers were depleted and the undead threat there was removed by some adventurers. The present location of the whole Greff band is not known.
