Grandfather's Rain offers a well structured, flexible adventure perfect for introducing both players and GM's to the smooth yet old-school play of Kevin Crawford's 'Other Dust'.

The module is a good example of the interesting and dynamic environments anyone can create using the sandbox mechanics that feature in Other Dust and once the proposed story-line is exhausted there remain plenty of adventure possibilities to explore in this FREE publication.

Use this as the foundation of your campaign or adapt the material to the system you enjoy most. I think you will be pleased by the useful content and hopefully encouraged to explore more from the talented Mr. Crawford.
