Early life[]

Byron Sully is born on a ship somewhere between England and America to Mr. Sully, a regular farmer, and his wife, Mrs. Sully. When they move to New York, Mr. Sully misses working on the land and dies. Mrs. Sully cannot cope with it and drowns herself in the Hudson River when Sully is ten. After he has lost both his parents, Sully meets Daniel Simon who becomes his best friend. They grow up at the docks together and in 1859 go to Pikes Peak near Colorado Springs to work as miners, in the hope of finding gold. In the summer of 1859, when working in a silver mine near Cripple Creek, Sully is trapped in a cave-in for 22 days and Daniel digs him out, saving his life. In Colorado Springs, Sully meets Abagail Bray and Daniel moves on. Sully and Abagail fall in love and marry against her father's wishes and Sully builds a homestead for her outside of town. Abagail gets pregnant, but she dies in childbirth along with the baby, Hanna, in 1865. After his tragic loss, Sully joins the army, in the hope of dying in the war. He becomes a sniper and his first target is a confederate major. Sully is told that the man is working on explosives and that killing him would save many lives. Sully kills the man, but feels very guilty about it. He finds out that the man had family and that he has been lied to. The major was not working on explosives but was a business man. With his death, the war contracts and his money going to his rival. Sully deserts and goes back to Colorado Springs, where he joins the Cheyenne and adopts their way of life.
