The Warmaster's command grotto was a room grown for Warmaster Nas Choka. Located deep with the bowels of Supreme Overlord Shimrra's Citadel, the command grotto served as a war-room for the Warmaster, where he would consult his Supreme Commanders, Battle Tacticians, and high ranking Priests and Seers. The room also featured a yorik coral niche which contained blaze bugs, that showed representations of enemy movements in far off systems.
