The Heroes of Heaven's Height
Within the northern slopes of the Mountains of Summer sits a valley, well below sea-level, nestled within a largely barren strip of the nation of Harborhead. From the stony fortress within its shadowed depths a cold emanates that affects the entire valley; scrubs alone grow on the ground and on the craggy cliffs that climb around it grow scraggly juniper and mistletoe trees.
The locals call this place Coldhouse, and it is the bastion of the Deathlord called Eye and Seven Despairs.
The Harborheadites and Sesus Tei-du largely ignore it. Upon her initial appointment, the Satrap attempted to dislodge the Deathlord, but only succeeded in losing the majority of the 17th Legion and a handful of Immaculate monks, and exposing herself to rebellion and more raids by fae warbands. Since the Deathlord seems content to sit in his valley and has never actually raided his neighbors or threatened anyone, House Sesus decided to let the matter lie.
