Paps of Scilla
Mentioned in Equal Rites, the Paps of Scilla are a range of gnoll-infested hills straddling one of the major trade routes, from Zemphis into Ankh-Morpork. There are eight of them. People have often speculated on who Scylla was, and deeper thinkers have wondered where she bought her bras. Mentioned as a hold-out of the last wild Gnolls, by Going Postal, the area is described as "pacified". In Raising Steam, the railway line to Überwald was driven through the Paps. Scilla's opinion of this is un-known.
