Don't forget about sanya: his faith is in communism (or really some obscure branch of it). He's a knight of the cross. If he can be that, then certainly there can be a true believer of socrates's teachings, or maybe those of other plilosiphers

They dont need the rituals to feed. They can just fight for that. No need for all the ceremony. A drunken bar brawl will do just fine (though most of them wouldn't do that.)

I don't think so... unless your character was already a wizard/sorceror or he/she was under the tutelage of an experienced seelie magic user within the court.

I have my own ideas on the subject, which are not based in any legend (cuz I'm to lazy to do research). Jade court would mainly be based around martial arts and grace, and not that malevolent at all: They have inhuman/supernatural recovery and inhuman/supernatural speed. Their catch would be damage through unarmed combat. They would also have a natural aversion to weapons. They then have their own special, secret martial art that focuses on their inhuman speed. They also mastered many other martial arts. They are made through a test of ritual unarmed combat. If they pass the test, they are given a jade armband that a spirit is inhabiting, and they gain the powers. They feed through combat. They are cured by losing in true ritual unarmed combat against a non-jade court vamp. What do you think?

The jade court is embroiled in mystery, and I think that many of us rpers would love to use them. I think it would be a good idea to compile ideas about them.
