Oh no, not at all. ^^; It's nothing like that.  It's just that I feel a bit too awkward since I barely know anything about the actual series, plus I don't really have much of a character idea other than "pegasus knight" and yeah. ^^;

I'd urge you not to give up, that this is basically a fantasy RP with some fancy terminology.  Often it's enough to start out with just three words, as Sapphire said, and that's enough to go.  For Sanguin, I did 'masked wolf girl'.  I looked at the circumstances and whether I wanted to make a werewolf or not, so I decided to make it symbolic.  So I thought about what characterizes wolves, and why Sanguin would wear the mask of one.  I thought about several things I hadn't done yet among my characters, being 'sword and shield' 'single-sided sword' 'alternate ego' and 'asexual', and then lumped in the traits of a wolf--family love, fierceness, fighting spirit.  

So, you've got a pegasus knight.  Knights, with their expensive armor and typical fighting prowess, usually come from wealthy or at least important backgrounds, so you've got a basic premise.  Lots of people in these times have horses, but pegasi are far rarer.  How did your character get a pegasus, or why did he or she choose one in the first place?  Are they a free spirit, wanting to pursue the life of a warrior for posterity's sake and to make sure the family name doesn't fall into ruin, but wanting to do it their own way?  Did a dying friend give your character his pegasus, and inspire your knight to follow in his footsteps?  Is your character from Bravura, with a personal stake in the war, or from Panoply, and eager for wealth or fame?  Or perhaps a hedge knight, banished from service in Augur following a bitter defeat?

Infinite possibilities wait after only a few words.
