Looks good Demik, but since the third characters are going into the Underdark, I don't think a horse or falcon will work. I am not against them, the idea works, just the horse especially wouldn't travel well in the Underdark. It could be taken down but it couldn't see, and some areas in the Underdark it simply wouldn't be able to traverse. The Falcon might work better, but some areas in the Underdark are so confined that a Falcon couldn't even achieve any flight without slamming into the ceiling.
