This massive keep is a district in its own right, filling the space where the five wards come together. The heart of the sanctum is an ovoid tower built from stone, crysteel, and sentira. Almost eight hundred feet in height, it can be seen across the length of the city. The outer foundation is a fortress in its own right, housing the Eidolon's personal troops: over a thousand Taskaan shifters, along with Inspired shock troopers and members of the Horned Guard. Farther in lie the quarters of the Chosen, where young Chosen train in the psionic arts and prepare to take their places in Riedran society. The central tower is the heart of the Iron Gate, and Tureya and her subordinates analyze Riedran trade and diplomacy and discuss plans for the future. If someone was looking to recover a manifest of Riedran shipping imports for the last year, or to determine if the Iron Gate was supporting the dreamlily trade, odds are the knowledge is locked away in the great tower.
