Empyrean Fortress A fortress is any large structure made up of Empyrean fortress walls and some times towers. There are many fortresses scattered across Dereth, some of which became occupied by Isparians (Dryreach, Lytelthorpe, Fort Tethana, Fort Witshire). Though they are Empyrean ruins, the Hea Tumeroks of the direlands learned to mimic the design and construct their own forts.
