Okay, so if we're starting off at about book 45, then roughly 2-3 years have passed since we found Elfangor (the only possible way we could've gotten the morphing power). So we need to alter our character's ages appropriately.
Q, if your character isn't/hasn't been in the group the whole time, you'll need to explain how we met up.
Tobias, unfortunately I know you like unmorphing Tobias; but it's more than likely you've recovered that ability by now since we're at book 45.
Well, if no one else will take up the mantle, I will.
