I dont know about you, but to me, this relates (generally) to wizard101 and Bartleby is (low and behold) in Wizard City.
Wizard 101 Forums -> Wizard City Forum -> This thread. Adds up to me.
Since Bartleby's sister is a Raven, I guess that covers land and sky. The next logical step would point me to the sea... maybe we'll find out he has a brother (or sister) that turns out to be some form of the Loch Ness XD
