Thanks for adding this in Eric but I think you are off here. The first person that comes to mind when I see "Alphatian Mage" Is my old apprentice and the second would be the head off the new school of magic.
Now your next comment. When I see "We don't know anything about this mage, including what his name is." Well then that obviously the Glantrian mage and If this whole page should be towards him I think hed be a liitle peeved that you called him the Alphatian mage ...... but then he's an NPC and you cant piss off an NPC when you are the DM, But hopefully you can get on his good side by correcting the DM on these little over sites.
Last point. "High level. Definitely higher than you." At one time that would be a great feat ..... not many are higher level than I was. High level. Definitely higher than you.
We don't know anything about this mage, including what his name is. He just seems to appear and interact with us, which usually leaves us better off.
