In the deep reaches of the Underdark, one xorn has filled a maze of tunnels with gelatinous cubes. Instead of attacking travelers for their precious metals, this clever xorn chases them through its maze, waiting for them to turn a corner too fast and run right into one of his pet slimes. In time, the gelatinous cubes digest the flesh and drop the precious metals for the xorn to pick up at its leisure. This symbiotic relationship keeps both xorn and cubes conveniently well-fed. For the unsuspecting adventurer, however, becoming the meal is far from convenient.
