My soulmate (Αδελφή ψυχή μου)

Harry wakes up after having a nightmare to find a crow with a broken wing outside his window. Bringing it inside to give it some food and water and to bandage the wing, Harry hears things he wasn't supposed to. Now at gringotts, he finds he has two dominants and neither are human. This is a Harry/Caleb/Acheron paring. There might be others later.
