The gate to the 60th floor creaked open, revealing a massive chamber bathed in the dim red glow of stone torches fixed to the walls. The air inside was hot and trembling, as if she had stepped into the heart of a volcano. Every step Sylvia took into the room felt like descending into the bowels of the earth itself heavy, oppressive, and saturated with a metallic stench that stabbed at the nose.
The floor was made of huge slabs of cracked black stone, and at the center lay a massive rune circle spanning tens of meters in diameter. Scattered around it were piles of bones and broken weapons, signs that this place had long been the grave of challengers who failed.
From the shadows at the far end of the chamber came a deep, heavy sound like the rumble of a mountain splitting apart.
DUUUM… DUUUM… DUUUM…
The tremors crawled up Sylvia's legs, enough to make some of the zombies in the rear ranks stumble slightly.
