Lone Warden

Book of Dagon
Out in the hills, the last of the templars gathered building a refuge for remaining Christians. There, they were ambushed by the armed forces of the Church of Dagon and the allied houses that followed it. All the templars were cut down and left to rot, all but one. He knew he'd need an army to defeat his oppressors, and by practicing necromancy, he found a way to bring his comrades partially back to life. But this obsession took hold of his soul and made him an iron husk, only living to fight for something long gone.
