Are there currently any WIPz or even RELz that add whole new factions or guilds to the game?

I always loved playing new guilds and factions in previous TES games and advancing through ranks. Unfortunately Bethesda had to mainstream Skyrim and cut the "true" Rank andvancement out.

There's a http://www.gamesas.com/topic/1384079-relzwipz-hunting-in-skyrim-guild-perks-prices-challenges-and-more/ mod--still in progress, but with an initial release that adds a few quests.

Awesome! I wish somebody would TRULY make use of the RADIANCE system! There was an attempt, http://www.gamesas.com/topic/1373997-relz-radiance-a-simple-immersion-booster/ , but it's been dead in the water for a while.
