Nergaoul is an ancient, evil spren and one with which Taravangian hasn't the resources to tackle. Adrotagia implies that Nergaoul is a Voidspren, or perhaps an Unmade connected somehow with the Thrill.[1]

According to Taravangian, the Thrill only affects people who are in a certain proximity to Nergaoul.[2]

Nergaoul's power was once bound to the proximity around Alethkar, but with Taravangian's conquest of Jah Keved, it is moving further west.


"The Thrill is at least as strong here as it is in Alethkar.  Maybe stronger.  I will speak to our scholars.  Perhaps this will help pinpoint Nergaoul."

–Adrotagia to Taravangian[1]

Nergaoul was known for driving forces into a battle rage, lending them great ferocity. Curiouslay he did this to both sides of a conflict, Voidbringer and human. This seems common of the less self-aware spren.

–From Hessi's Mythica, page 121[3]

I am convinced that Nergaoul is still active on Roshar. The accounts of the Alethi "Thrill" of battle align too well with ancient records - including visions of red mist and dying creatures.

–From Hessi's Mythica, page 140[4]


Brandon has confirmed that the Unmade are Splinters of Odium.[5] Odium splintered himself and created the Unmade to be his influence on Roshar. It is through the Unmade that Odium may be able to influence people in how they think or act.[6]


Nergal was the Mesopotamian god of pestilence.[7]
