Students at Brewkessel were sorted into four houses based on personality and magical predilection. Although the Cornuthaum of Selection was lost with the rest of the castle, Brewkessel alumni have passed down the magical traditions of the houses down through the decades. It is not unusual for someone to describe themself as a "Phoenessent Alchemist" or a "Kelpulous Necromancer," despite never having set foot in Brewkessel.
