One of the largest caverns in the cave system that makes up the Base. Stalactites and stalagmites several meters thick at their widest adorn the 'hall' like rows upon rows of columns. The roof of the cavern is high, high above, and marked with many arched impressions, as if it has been hit many times with a gargantuan mallet. Made entirely of a pale grey stone, the 'Hall' is lit by great orbs of light that swirl from pale green to white to blue and back again, lofted in each of the pockmarks in the ceiling and occasionally flickering like strangely-shaped flames. Large tables, made from the smaller decapitated stalagmites, are scattered throughout the cavern and laden with food of various types, kept fresh at at the proper temperatures by the same peculiarity as the light orbs.
