Basically:
1 The setting was not supported anymore. Originally new material was incorporated into the website. Then that stopped, people would write large texts that were basically "ignored". Can´t blame anyone since people got other more succesfull things to do.
2 There was no bible to the setting. I got tired of telling people that there are no gods when they came up with their cool gods and finally didn´t feel like correcting people since I didn´t have official status to tell them that. Basically the setting was being redone over and over again instead of being fleshed out.
So if you want it to live up:
1 clean up the website, it seems to be down for the moment.

2 Post the artwork that was commisioned: I got people working in the industry doing a few pieces. Still have them in my harddrive.
3 Give people jobs and authority. Shared responsibility is NOBODYS responsibility and without authority it becomes a drag trying to help people.
