Taking inspiration from Peregrine's excellent idea.
Hiems considers learning Castillan, but, not only can he often make do with Catalan or Latin, he doesn't feel that much social, especially given the effect he has on people. He doesn't want to go to the school to find himself become its only student.
So he'll keep to himself, and settle.
As I see it, he's got the rudiments of a lab (-3 to all totals), so he'll spend the season bringing it up to shape. At the season's start, he'll probably take a day or two to inscribe various circle enchantments in order to protect his tower.
