The Bonecrunch Hills rise along Aal Salma's western edge, a troll-held range that has resisted settlement since before the oldest Salmani records. Troll clans have occupied these hills for generations, and the name tells travelers what awaits those who ignore that fact.
Aal Salma maintains a working truce with the hills' inhabitants: the lowlands stay out of troll territory, and the trolls stay out of the lowlands. The arrangement holds more often than not. Merchants who venture into the hills to trade for bone-work and hides either return with valuable goods or don't return at all. A handful of troll mercenaries have found irregular employment in Aal Salma's less visible enterprises—expensive, unreliable, and effective in ways that discourage close questions.
