I'd like some action mixed in this, something where the RPers would have to band together to fight against someone. How about something where some other species is trying to cause conflict between the Seelie and Unseelie courts? The 'villain' in this story wants Fae powers and has figured out a means to harness them. But they need the royal family weakened to make their move. So, perhaps they frame a member of one of the courts, or attack fae to make it look like the other court did it ; something big that would cause them to declare war on each other. This is where the RPers would come in. Perhaps we're a group hired by someone who believes that neither court is at fault. Or perhaps we discover it ourselves and form a group. Either way, there'd be a mixed number of people from both courts who work together to fight.

...I think I got a little carried away. >.> I just had a sudden plot idea and decided to write it out. xD
