Eliza had been in the house for a week, and boredom was starting to set in. The vast, empty rooms offered a blank canvas, but also a tedious routine. A sudden impulse made her drop the feather duster, and with a giddy smile, she dashed to the basement stairs.

The musty air of the basement always felt thrilling. She hummed a little tune as she searched, her fingers tracing the cold, rough stone walls. She wriggled her toes against the damp floor. It was a game.

Behind a particularly ominous looking bookcase, she found a panel that sprang open at the slightest touch. A grin stretched across her face, mirroring the anticipation bubbling inside her. "Well, hello there," she whispered, and stepped into the darkness.
