Daring Do and the Catacombs of Causality

The Typewriter

You're in a large vaulted room, lit by sconces embedded in the wall. On the East are two exits, the upper one accessible only by a broken stairway.

You are seated at your typewriter, which is adjacent to a small section of your home's wall.

Stand up.

Use the typewriter to write a happy ending to the story you're in right now.
