Ahhh!!! We are working to get some bare bones stuff up so people can start here soon!
The breed profiles are up over at
StarLightAdmin if you want to browse the down and dirty descriptions. :3
The most I can offer herd wise: Draak is dark and broody, Luumen is sparklepony central, Caitiff is full of outcasts and exiles, and Pindan is some desert ponies who don't want to deal with anyone else.
