Dornishman

Ser Bonnifer Hasty, now on Harrenhal, is a very pious man. Bonnifer thus seems to be a refrence to Bonifatius, name of several popes, and originally of a Saint, the so-called "Apostle of the Germans", who did converting among the Germanic tribes (especially here in Hesse, where the Diocese of Fulda is in his heritage) and was slain by the Freesians. Lets see who slays Bonnifer when the curse of Harrenhal comes ;)

Apparently, the sword Dawn was made of comet metall. The same hodls true for the sword Dorn in Williams' Memory, Sorrow and Thorn. The names might just be similar enough for it to be hommage, reference or inspiration. /Edit: Hm, and Dawn is also located in Dorne...
