I'm considering writing up a character for this, if it's not too late. (Based on taking a quick glance over the IC posts, it looks like I might still be able to join the group before everyone heads out.)
Edit: Although one small note: I would prefer to detail the appearances of the human and the dragon by writing a detailed description, rather than using artwork.
Second Edit: I have a question about dragonrider combat, since they're described as protectors. Do dragonriders fight from the backs of their dragons (depending on the dragon's size, of course) or do they dismount to engage opponents? The answer may affect my character's choice of weapons and armour.
