Wheel of Time based RPG, is set about 200 years past TG. There are three towers, not quite fighting for power, Light, Twilight (Balance) and Dark. The Twin Towers RPG was started on 2/20/2000, and in the beginning there were only two towers (hence the name.)
The light and the Dark were officially represented as towers, and the Central Pavillion was the undeclared medium, which housed the library, commons, meeting rooms, cafeteria, novice quarters, and other neutral necessities.
A few months after the game was started it was decided that enough people were interested in Balance between the Light and the Dark, and so the Central Pavillion was renamed the Twilight Tower. (Twilight mostly applying to the times of day which bridge the light and the dark, appealing towards an equal balance of good and evil, and everything in between.)
Having amassed more players the Towers are has also expanded. The novices, or Isai, have thier own quarters. There is a hall devoted entirely to the healing arts. The entire area has been named the Valley, and encloses all these buildings and more. Right outside the vallyer there are a few good sized towns, with the normal sprinkling of pubs, smiths and the like.
However, with the agricultural developments and planning of the three Amyrlins, the Valley can be self-sufficient if need be, even without Travelling for supplies.
