"Born in the heart of a sleeping volcano, Varkros is a living stone shaped by fire and pressure. The Void could not corrupt him—it only cracked his surface, letting more heat escape. Now he walks the battlefield as an unbreakable force, daring enemies to strike him." 

Varkros should feel like a living mountain - slow, heavy, inevitable. Not emotional, not aggressive, just an unyielding force. A slow deep voice, rumbling, speaks like something ancient.
