Thrylheim is the ruined city of the frost giant nation that once controlled much of the Fog Peaks. It was destroyed in a devastating war with the white dragons of the mountains and is now largely in ruin. Underground portions of the city are still said to exist, and hold the frost giant sword Eldavar, used by the last konig of Thrylhim, Virtosk, to kill the elder white dragon Keljanir.12
