In World of Warcraft, Void lords (most likely "lesser" void lords and first encountered in The Burning Crusade expansion) are the second most powerful type of voidwalker yet encountered, beside the void gods. They are gigantic and armor-plated. They usually cast shadow magic. Not much is known about those creatures, but that they probably lead the voidwalker race and that they constantly feed on magic or life. One of the most powerful Void Lords is probably Dimensius who devoured the Ethereals' planet.

It is unclear whether the in-game entities are the same category as the "Void Lords" defined in World of Warcraft: Chronicle Volume 1. In this source, void lords are said to be composed of pure shadow energy, and are monstrous entities. These beings are cruel and merciless beyond mortal comprehension. Driven by an insatiable hunger, the void lords seek to devour all matter and energy in the physical universe. The void lords exist outside reality in their natural state. Only the most powerful of these entities can manifest in the physical universe, and only for limited amounts of time. To maintain their presence in reality, the void lords must consume untold amounts of matter and energy.
Old Gods are malignant entities created by the void lords, and they live only to transform the worlds they infest into places of despair and death.
