iaza consists of six large stone domes that form the points of a hexagon, with walls filling the gaps between the domes, and a single squat tower in the center. Each dome contains a single sanctum and quarters for servants and custodes, and has two gateways, one that opens to the inside and another to the outside.

Although unorthodox, the arrangement has proven workable. The conventum has almost no common resources: most magi maintain their own small libraries, for example, but some sharing does occur. Riaza has no common facilities for guests, but some magi have made provision for guests in their domes.
