The Crystal of the Saints was an ancient artefact that could bring the Faceless Ones back. In 2007 it was in the possession of Rancid Fines and Christophe Nocturnal. It was later revealed in Dead or Alive that Fines had held onto it in the thirteen years since his encounter with Skulduggery and was still trying to unlock its secrets. After failing to activate it once more and bankrupting his latest partner. Fines narrowly escaped Skulduggery and Valkyrie and resumed his search for a partner who could help him unlock the secrets. Later on, while time travelling with the Jericho candle, Valkyrie learns from China Sorrows that the "Eye of Rhaast" is the key to Damocles Creed's plan to start the Activation Wave before Malice brutally murders her. Returning to the present, Valkyrie and Skulduggery discover that The Eye of Rhaast and The Crystal of the Saints are one and the same. Rancid in the meantime tries to sell the Crystal to Christopher Reign, but Reign refuses to buy the Crystal and wants to destroy it due to his fear of the Faceless Ones returning and his distaste for Rancid's history as a Nazi. Rancid is extracted by Creed's men when negotiations fall apart and the Crystal is prepared fro activation. When Valkyrie sacrifices herself to stop the activation wave, the Crystal is charred and blackened, rendering it useless.
