I have a couple ideas. I was thinking about taking you out to a nice restaurant, if Chiron will let us out by then. If not, we'll consider it an IOU, and I've got a fallback present. It's a charm that will give you flight for about five minutes, but it'll need at least a minute to "recharge." There are a few, ah, kinks I'm still working out, but it'll be done by your birthday!
