Humphreys
From Tardis Wiki, the free Doctor Who reference
Humphreys was a student at an unusual school.
Humphreys 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 Humphreys 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.
Humphreys was watching his friend Karswell climbing a rope in the gymnasium when he was killed. Humphreys was traumatised by the death. (PROSE: Long Term)
