Graymark is the citadel of the Mord Wraiths, situated deep in the Eastland in the Ravenshorn Mountains. Before being used by the Mord Wraiths, the fortress was home to the Mwellrets.

Graymark is near Heaven's Well, the source of the Silver River. It was built by Trolls during the Second War of the Races.

Changes Made for the TV Adaptation

  • In The Shannara Chronicles, Graymark is not a castle for Mord Wraiths or Mwellrets, but for Gnomes. It has been taken over by the Crimson, who are using it as their base of operations.
