I've written several levels for an online multi-player text-based game called Federation.  It has a space fantasy theme, so the different story scenarios are organized into planets.
  

On Bosky, where technology has been all but outlawed, the people are uneasy about the upcoming full moon.  Explore ancient moss-encrusted buildings, hike through groves of strange blossoming trees and follow an underground river to a now lifeless ocean.  With only your dreams to guide you through the mists, can you uncover the secret of the mysterious forest-dwelling druids?  You may be the planet’s only hope.

Clicking on areas on the map below brings up close-ups.
I've posted a step-by-step walkthrough that gives directions.
If you are not ready for full spoilers, check out the instructions- 
a milder version that doesn't give quite everything away.
