There is no hard CDQ requirement for most of the ranks, as with good ingame roleplay and development thread one can attempt to illustrate in the Lucinda forum why a character should be noticed and moving up. Dawnwoven would require at least one, I imagine- it's the first level where one is endorsed to teach (at home or abroad), whereas levels below clerics teach but don't really have official backing. Nightwoven would be an epic, yeah.
