Runhope never knew his father. His mother told him, before she died, that he had been a miner, captured by unidentified humanoids when isolated in a rockslide, and sold to Drow, who, in turn, put him to work in one of their mines. The man was mated with the mother of Runhope, who was born into slavery among Drow, by arbitrary choice of their masters.
This woman, Sempori, was sold to a wizard after the death of her man, while pregnant with a boy. She was wise enough to train the child to act stupid and servile, but taught him the human language. Sempori died in the boy's seventh year.
An accident in the wizard's laboratory burned most of the boy's hair off the top of his head, and left scars there and on his face, for which they called him "Quughuth", meaning "marred", in Drow. His mother secretly called him "Runhope", with the wish that he would break forth to freedom.
The wizard kept Quughuth as a laborer, guard, and tinkerer, though not skilled, noticing, but underestimating, his intelligence. In addition to learning to clean, fight, and mend, and to understand Human and Drow speech, Runhope secretly learned to work locks, and undo traps, and furtiely spied on the wizard, when he knew no one was around, including the wizard's familiar, he studied the arcane arts.
He patiently practiced in secret the cantrips that others could use openly, and when he was ready, he stole some spellbooks and made his way to the rumored Sanctuary.
It was a dreadful trip, crawling through tunnels, hiding, unmoving, for hours until he could hear passing creatures no longer. Though luck was on his side, he spent much time dazed by fumes emitted by battling monsters who were unawared that he hid nearby. His fortunes held, though, and he made it to Sanctuary, even if he could never figure out exactly how.
Now Runhope looks forward to the future, with hope for making a place for himself in Sanctuary, or even tin he World Above.
