Graywall is built atop the ruins of Korash Khaar, and the fortress of the Dhakaani goblins stretched deep beneath the earth. The fragments of history suggest that the final attack that broke the Dhakaani defenses came from beneath the citadel. No one living knows just what lies below the Dhakaani tunnels. Almost all the entrances to the depths have been sealed, save for a heavily guarded passage in Bloodstone . . . the Deep Door. Xorchylic has allowed adventurers to enter the depths before, for reasons of his own; it’s also possible that PCs might learn of an unguarded passage to the deep tunnels. What lies beyond the Deep Door remains a mystery. Storytellers spin tales of aberrant legions locked in combat with goblin ghosts and of deep wyrms atop piles of Dhakaani gold. The truth might be more wondrous still, or infinitely more terrible.
