Hi! I've been running the Celestial Deliberative since this past October. Unfortunately, there are only 3 other regular posters apart from myself, and things have been getting slow and a little stagnant, so I thought I'd try for an infusion of new blood to help kick things into gear.
The default setting is a future version of Creation, almost 2 decades after the disappearance of the Empress, and 10-15 years after a group of potent young Celestial Exalted seized the Sword of Creation and established a Celestial Deliberative. Right now most of the action is focused on a Solar Half-Caste, her Abyssal Half-Caste twin sister, and a few of their friends as they go through high school (and fight Infernal plots) in the City of Makers, but there's no need to feel constrained in who or what you can play. Similar to the idea of manvantaras from the recent fan-made Nocturnal Exalted, characters from any world or setting can be played, including alternate versions of Creation closer to the default.
The Celestial Deliberative perfectly negates hostile canon, and while there is a certain *ahem* perviness (which should surprise no-one familiar with my work here) in much of what's gone on so far, you're under no obligation to participate if you don't want to.
