Round 344

The walls' synchronized breathing stopped completely—everything except that low pulsing hum growing stronger like a heartbeat counting down seconds until the next phase. Silra's grip on your hand tightened, her skin fever-hot against yours as she hissed urgently: "That passage... it's not natural. Something's calling us down." Her yellow eyes fixed on the dark opening that had just appeared in the wall behind you both. But even as she spoke of separation for your safety, her fingers intertwined more tightly with yours, refusing to let go. Three hours. That's how long she had before the corruption consumed her completely.
