Mmmmm not too sure what to do

So I have guild wars prophecies which I bought when it came out. Then I bought factions when it came out. Never played both more then a week but siince no game is out I kinda wanna give it a go. Problem is I registered them on different emails. So can I change the email for the same or something?

So I can play prophecies with a different class or something

Unfortunately I doubt that. Your two keys are effectively linked to different account. However you can always give it a try through their support page, providing proof you own both emails.
