Mordaunt was an evil sorcerer who was determined to claim Excalibur for himself. His knowledge of the sword and the mythology surrounding it, suggests that Mordaunt could have been present around the time of King Arthur himself, which was around the late fifth or early sixth century. This would have made Mordaunt at least fifteen hundred years old.


After Piper Halliwell removed Excalibur from the stone, Mordaunt appeared at the manor. He convinced Piper that she was the new King Arthur and that he was there to train her. He explained that the Dark Knight was after the sword and he conjured up a list of ingredients for a vanquishing potion.

As Mordaunt continued to train Piper, Phoebe and Paige went to collect the ingredients from Richard Montana. However, when Phoebe was about to add the last ingredient, Richard stopped her, revealing the potion was highly explosive. The sisters then figured out Mordaunt had tricked them and was after the sword.

When the Dark Knight attacked at the manor, Mordaunt revealed he had been working with the demon the entire time and vanquished him, as he was no longer needed. However, Piper, under influence of the sword, believed his lies, even when her sisters tried to warn her and take the sword away.

Mordaunt continued to seduce and manipulate Piper and worked with her to establish a new round table of demons. They gathered a Grimlock, a Banshee, a Creeper, and a Soul Blaster Demon. However, when the demons were about to swear their loyalty, Mordaunt finally betrayed Piper and used a spell to vanquish the demons and take their powers. He was then able to claim the sword and stabbed Piper, though Leo was able to heal her in time.

Knowing that Wyatt was the true wielder of the sword, Mordaunt set out to kill him. However, the sisters had anticipated this and set a trap. Wyatt then claimed the sword and used it to vanquish Mordaunt by stabbing him.
