The Hellscreamers are a group of elite warriors of G'valt formerly led by the fearsome Una Strongsong. They earned their name through their battle tactics, which consist of debilitating their foes with a terrible high-pitched scream before charging in to finish them off. The power of their voice is such that it can not only be used to damage foes, but also to propel themselves into the air, making them formidable, agile adversaries.
The Hellscreamers were tasked by the Corrupter to kill the Provokers in Stone Rift, but they were defeated, and Aerdon Saroscient killed Una Strongsong after the battle.
The Provokers encountered them again in the hut of Emory Suresteel.
