(Crossposted to a number of groups...)
Over at ENWorld, a few people - including me - have started to create a Wiki-based fantasy setting. It is based on the d20 system and intended to be 100% OGL material.
You can see the thread that started the project here
(discussion is still ongoing) and the Wiki itself is here
. The setting is intended to be a rather "generic" fantasy world, but one thing that sets it apart is that a huge war will likely start in the next few years of game time between two alliances of nations. This is not a "classical" conflict between "Good" and "Evil" - both sides have their admirable points, but also their fair share of villainy.
Participation in both the discussion and the Wiki are very much welcome!
