Something that's been bothering me: all these other sources that use gnolls. There's a Mage Knight gnoll figure, there's miniatures, gnolls are in practically every video game... now I seriously doubt all those people are going to pay royalties to DnD. I mean, how hard is it to create a doggish humanoid and just give it a differnet name? All of which implies to me that there has to be some folkloric, or similarly public domain, derivation of the term and creature. Danged if I can figure what it is, though.
