From PathfinderWiki

Bos-Phargrumm is an ice castle perched high among the peaks of the Tusk Mountains northwest of the Ginji Mesa. It is the castle of Jarl Gnargorak, the self-proclaimed king of all frost giants.12

The fortress is constantly built on top of the decaying older layers underneath, with the jarl and his most favored minions living in the newest, highest layers. Deep in the lower collapsed levels, many dangerous creatures make their home.2
