Discovered solely by the G’Noud, each shard contains kinetic properties that allow the use of tools without much in the way of manual exertion. The miners gather small hand sized bits of the glassy rock, all of which is chiseled off the central orb found deep within the Great Column. No one possesses the knowledge of just how great the orb is in size, nor will most speculate on how long it might last.

Elder folk had spun tales of its birth by a sheering and massive comet from the sky, crashing on the surface to its gradual and destined recession into the blessed ground where it serves all of subterranea.
