The Black Death
Alwyn is from the fallen covenant of Mistfen, and it was he who made his way north to Cad Gadu and alerted the order to the fall of his covenant and the betrayal of one of its magi. He has contracted a strange infection in one arm that has proven resistant to any magical healing and carries with it an infernal taint. The infection is slowly killing him, although the magi of Cad Gadu have provided him talismans that have slowed the process.
Alwyn does not like to talk about his past and seems fixated on revenge against the magi who destroyed his home. He is an accomplished tracker and woodsman, and knows the fens extremely well.
