AU Rejoicing in Their Strength (Lomonaaeren)

Severus went home after the war, and his father has trapped him there, mad after his wife's death. Severus escapes at times by astral travel. During one of his journeys, he is astonished to find Harry Potter living in the Forest of Dean. (Originally a Drarry Story by Lomonaaeren, but I altered and extended it.)
