Coombs are valleys eroded into the inner face of the Sacred Wall. These are the many indentations that can be seen in the model of Osrakum. The Great and the Lesser Chosen have their palaces and gardens built into these coombs. Only the highest Houses of the Great possess a whole coomb to themselves.
Coomb Suth is Carnelian’s ancestral home. The map shows the palaces set into the floor of the coomb. Above, carved high into the Sacred Wall, lie the upper palaces or Eyries where the Suth escape the summer heat.
