Abaddon's Castle rose like a majestic monstrosity in the center of the Underworld—a colossus of living obsidian, whose architecture seemed to grow of its own accord. Twisted towers and endless halls intertwined like the ribs of a sleeping creature, pulsing with raw, ancient energy. Scarlet lightning streaked across the Hellish sky, ricocheting off enchanted walls, while streams of arcane smoke rose like living spirals from the highest battlements.
There, at the heart of it all, Walpurgis was being prepared — the Feast of the Demon Kings.
