The Tanil Hills are known for their wonderous natural beauty and exceptionally pure springwater.
Clans of gnomes and dwarves live in caves in the hills, including the Glimmerfinger Clan of gnomes.
Hangman's Hill lies atop one of the hills near Deraheib. It is still used for occasional hangings by the judiciary of Deraheib. Near the gallows is an old house, which is the scene for the Judges Guild module The House on Hangman's Hill (https://en.wikipedia.org/wiki/House_on_Hangman%27s_Hill).
