ALT Hearthstone Reign of the Black Empire artwork showing the four Old Gods towering over a circular platform. C'Thun rises from the center foreground with a massive eye and smaller eyes across its body, Y'Shaarj appears on the left surrounded by glowing green energy, Yogg-Saron looms in the background with tentacles and a fanged maw, and N'Zoth emerges on the right with glowing orange eyes and dark tentacles. Standing on the platform below are the Titan-forged heroes Mimiron, Freya, Emerald Architect, Archaedas, and Amitus, Keeper of Amitus, facing the Old Gods amid swirling mist and shadow.
