Osvivum:
An XX class beast similar to Dementors and Lethifolds for its unkillable and dark nature.
An Osvivum is the soul of a deceased child, inhabiting it's own skeleton after death and bound to the family from which it was born. Some say an Osvivum exists as a tragic reminder that all magical children are to be protected.
- Or -
The attack on Halloween 1981 has a different outcome, and Harry Potter becomes an Osvivum.
Years later, when Harry gets banished from the Potter Manor and - in turn - his own bones, he decides to build himself a new body.
Third Person POV.
This is pre-slash Tomarry, meaning that these characters will get together in this timelines future, but not in this fic. This fic is complete, a sequel is unlikely.
