DeJoule is one of the villains from the video game Blood Omen: Legacy of Kain.
DeJoule was the guardian of the Pillar of Energy. Her body irradiated energy, frying anyone who got near her. Because of this, she had to wear a insulating cloak in order to contain her own powers. When she was corrupted by Nupraptor's attack at the Circle, she became insane and, along with Bane and Anacrothe, they created the Dark Eden, from where they started a plot to twist the land.
With their combined powers, they created a massive energy that steamed from the apex of the structure, creating a dome around it that started spreading through the landscape, leaving behind only a bizarre and twisted parody. DeJoule's powers powered up the structure and allowed the dome to spread fast. Kain, after meeting with the vampire Vorador, proceeded to the Dark Eden to kill the corrupted guardians. He finally meets the three guardians inside the place, but Anacrothe runs away and summons Malek to help them. Kain then summons Vorador, making Malek angry and neglecting the other two.
Bane and DeJoule then escapes to a open area, where they fight Kain, while Malek take on Vorador. The two tag up to fight the vampire, with Bane creating puddles of water to trap Kain while DeJoule fires blasts of energy from a safe spot. However this was not enough, as Kain kills both of them.
