Chasm

Nora stood on the edge of a deep, dark chasm, that ran through the middle of the street. She peered down. The chasm stared back. She could just barely make out something down there; it was large, and a deep purple that was nearly indestinguishable from its surroundings. And horribly enough, it moved, as if breathing. Nora shuddered.

There was no safe way across the chasm as far as she could see.
