Abney

 was a student at an unusual school.

Abney came from a society so advanced that it could predict when a child would commit a violent crime decades in his future. They removed these children, of whom Abney was one, from society and placed them in a school where they would not age.

After the boys had been at the school an unknown number of years, a corporeal expression of their future deeds began roaming the school, killing the boys in a violent fashion.

Abney was killed while he searched for a book in the library. (PROSE: Long Term)
