The command grotto, belonging to the Warmaster Nas Choka, was a chamber cultivated specifically for him. Situated far below the Citadel of the Supreme Overlord Shimrra, this grotto functioned as the Warmaster's war-room. Within its confines, he would confer with his Supreme Commanders, Battle Tacticians, and esteemed Priests along with Seers. Further, the space included a yorik coral alcove holding blaze bugs, which visually displayed the movements of adversaries in distant star systems.
