Searching for the Holy Grail, Vortigan arrives in the village of Oxleigh, known for its middlemist flowers, and ransacks it, killing all of its inhabitants except one girl, Nimue, and burning it to the ground. Not finding the treasure, he continues on to the next village, Camelot, and spies on Merlin and Nimue, discovering they have the Grail in the process. When they arrive in the ruins of Nimue's village, he approaches and follows them to where the first fire made by mankind is, and sees that Merlin has reforged the Grail into Excalibur. Even so, he demands the sword, and stabs Nimue in the chest when she attacks him and rips off his mask. Heartbroken, Merlin threatens him, but Nimue, having drank from the Grail while Merlin wasn't watching and become immortal, rips out Vortigan's heart. Despite Merlin's pleas, she crushes it, killing Vortigan and turning her into the first Dark One. Completely corrupted by the Darkness, Nimue adopts Vortigan's mask and cloak. ("Nimue")
- According to legend, Vortigern attempted to build a tower which would not stand. He was advised to sprinkle the site with the blood of a child with no father. In the accounts of Geoffrey of Monmouth and many others, this child was Merlin. The boy saved himself by revealing the true cause of the tower's collapse: Two dragons fighting beneath the foundation. According to the Welsh Triads, a set of medieval manuscripts, Merlin predicted Vortigern's death after this revelation.
