Nasir was a renowned if somewhat eccentric loremaster of the Briskwater Academy, who preferred the company of other intellectuals, and were known for being a bit of a bitter and snobbish person. He was the mentor of Mirasol.
Upon meeting The Party he provided them with the means of entering Castle Caerlinn, and agreed to study Valkyrie's notes about her astral projections. He returned to Briskwater for the Blazing events, but did not participate in the festivities.
