PoE Credits Music

Hey everyone, I'm interested in the name of the song on the ending credits, I have googled I am on exile but I couldn't find anything, also I am wondering if you can get this song by buying an supporters pack? I bought one a while ago - before Dominius was added - and this song wasn't there yet.. can I buy it now? which package do I need?

thanks.
