A -- something in the Errant Road on-line free-form role-playing game. What? Very good question.
More or less, Growf appears to be some supernatural figure -- whether deity or demon is unclear -- that the trolls in Errant Road maybe worship, maybe fear, or at least, swear by. We've heard his name invoked in vain by PC Grope and assorted relatives, generally in a cuss-word context but not always. He has also given his name to a few geographic features, notably the troll term for the Waldhaxen Channel, which they call "Growf's Drainpipe."
