A quick search didn't reveal any other topic covering this so I decided to make one.

I was wondering what other people had done with these plot hooks.  Who's used autumn or spring fae, jade court vamps?  Has anyone tried to make blue, yellow or grey court vampires, or other supernatural gribblies.

I'm running a game based in London.  The spring and autumn courts are groups of changelings who have figured out a way of stabilizing their nature somewhat.  They have a much weaker impulse to make the choice between mortal and fae.  These courts also have an agreement with the queens so that summer and winter have limited power and influence in London as long as the changeling courts maintain the Accords and relative peace.

EDIT:  This is just simple curiosity.  I'm planning on using the spring/autumn court and was wondering how others used the same idea.
