The atmosphere within the Sloth Domain Castle was a blend of ancient mystique and modern elegance, its every corner steeped in a heavy, pulsing power that echoed through the polished hallways. The fortress itself, carved from dark marble and laced with veins of otherworldly minerals, gave off a faint luminescent glow, shifting like the heartbeat of the castle itself.
High, vaulted ceilings arched over spacious corridors adorned with intricate carvings and murals, both historical and technological in design, all lit by torches burning with ethereal crimson flames. The flickering light created shadows that danced across the hall, casting an eerie beauty over the modern, high-tech elements woven seamlessly into the architecture.
