This page lists the architects of the dream worlds, so to speak, and a brief description, as well as information on which maps they have made, when their last update was, and relevant contact information. This page is a work in progress and some authors are more active than others, so their dates may be inaccurate. Dates are in international standard; ie, yyyy/mm/dd.

The Six-Month Rule is an agreement between the authors, that if an author fails to update within six months of their previous update, then their maps may be freely edited by other authors (unless otherwise specified). The rule is reset when they update again. It's a pretty good litmus in determining whether an author is active.

If you are interested in contributing to the game's development, please take time to read the Content Contribution Guidelines.

This page is under construction. Dates are based on the latest version.
