What Happens When You Lock Up An Immortal Man For Eternity?

A man finds himself locked up in a small room all by himself, unable to escape. This story is about how he figures things out by himself, with nothing to help him except a stone with a single word carved on it.

This is a fantasy story set inside a reality I have created. Progression is technically slow-paced, but beware that time runs quickly, and my chapters are short.

WARNING: I'm not taking this seriously and will write whenever I feel like it.
