After delivering the Amulet of Kings to Jauffre, he will offer his paint horse, which is in the priory stables, as assistance. He can also be asked about his fellow monks, if his disposition is high enough.
He is killed by the Mythic Dawn when returning with Martin Septim to Weynon Priory. However, Jauffre will still give his horse to the Hero. He wears a weightless Black Robe, which are quite rare in the game.
