Kergrim

Kergrim were horrible creatures of the Underdeeps. Vaguely Troll- or giant-Frog-like they were often guessed to have been descendants of Troll-kind that had been magically warped by the Mordo. Kergrim always appeared where there were ancient Tombs and relics of the dead, and they were believed to either feed from the dead or to be attracted by the vapour of massgraves and cadavres.
