DeJoule was born to serve the Pillars as Guardian of Energy at some point in the centuries following Nosgoth's early history and, along with the immortality gifted to her by her role, DeJoule's position also allowed her power over the "harnessing and manipulation of energy" which had somewhat altered her physical state, meaning that she naturally glowed with "intense energy"*. The Pillar Token gifted to DeJoule was her insulating Cloak; which served to gather her energy and protect both DeJoule and her fellow Guardians from harmful discharges*. When the cloak was discarded, her powers would be unleashed and she would become little more than a glowing humanoid outline.
In Blood Omen, Kain's quest diverted him into the Termogent Forest, seeking Vorador's aid in defeating Malek and when Kain emerged he spotted Dark Eden and the dome of energy rising from the tower. Suspecting the involvement of corruptedpillarGuardians, Kain travelled to the Dark Eden; passing unscathed through the dome and witnessing the hideous mutations of nature within.
As Kain reached the tower at the heart of Dark Eden and found the three guardians responsible, DeJoule was initially keen to fight Kain,seeing him as a "whelp", but Anarcrothe denounced this as "ridiculous"* and summoned Malek to defend them before Teleporting away, leaving DeJoule and Bane to escape on foot. Summoning Vorador to face Malek, Kain pursued the two Guardians outside and confronted them. As Bane laid water traps for Kain, DeJoule hung back at the edge of the battlefield on a small island in a water covered area and removed her insulating cloak, unleashing her powers and turning her into a glowing form. DeJoule summoned several glowing spheres and attacked Kain using energy projectiles. After killing Bane, Kain turned his attention to DeJoule and killed her.
DeJoule is mentioned in the background to Nosgoth in the backstory of the Alchemists and the red sisters of Anacrothe - where she and the rest of the Dark Eden triad are cited as an example of the elemental knowledge that was lost and became legend to the Humans under the rule of Kain's empire in the Soul Reaver era.[1] DeJoule was also mentioned in the background to the Beastmaster class, where it was said that she and the other members of the triad were worshipped by the groups of mutated humans that lived in Dark Eden after the fall of the triad - ultimately giving birth to the 'scourge of the wild' faction that sought to tame nature and the environment to their control.
Notes
DeJoule's name is likely based on the International System of Units (SI) unit for energy (or 'work') the Joule; itself named after English Physicist James Prescott Joule; the reason for the 'francophonic' version is puzzling, though hardly surprising given the 'French' reputation of the Metric and S.I. systems. An "Energist" can be taken to literally mean "one who alters the condition of energy"
DeJoule's age is not conclusively discussed in the series, but since we know that an Energy Guardian was killed by Vorador in Nosgoth's early history, DeJoule cannot be older than 500 years at the time of the events ofBlood Omen(It is not clear if DeJoule was born as a direct successor to this guardian, or years later after the death of another).
