Pale orc

Pale orcs, also called the Pale, are fallen orcs that despise all that is good and holy. They are deformed, sickly orcs that are defined by visibly pale skin and glowing eyes, who lived on Draenor before its destruction.

Background
The pale orcs draw on the power of K'ure and Cho'gall says they are the key to subjugating him. Cho'gall, referred to as "the master", has taught the Pale how to use the Void and through it enslave elementals.

When young orc shaman from around the world come of age, they make a pilgrimage to the Throne of Elements to seek the blessings of the elemental spirits. The entire journey is filled with risk, but the ceremony itself is the most dangerous time of an orc’s life. It’s not clear what happens to those who are not strong enough and succumb to terrible visions and unearthly whispers during what should be the triumph of their young life. Those orcs who fall to the otherworldly voices flee their clan and become the Pale, withered remains of their former selves, hiding from the light and babbling incoherently in dark caves. It is unknown if they are truly insane or have made contact with a malevolent force. The answers lie in the twisting caverns beneath Nagrand, where some of the largest colonies of Pale linger and speak cryptic warnings.

Following Cho'gall's siphoning of K'ure's power, he led the Pale to attack Highmaul.

Appearance
Pale orcs are deformed, sickly and pale-skinned. Their skin colors range from a white to a light gray. Pale orcs' skin courses with a blue or green energy. Their eye colors are usually the same color of the energy. Unlike standard orcs, pale orcs walk on all-fours. When they stand all the way up, they are practically squatting.
