Horus has led a poor life. He was abandoned at a young age because of his lineage and was never adopted. Once he was too old they threw him on the streets where he begged every man and woman for mercy. He survived day to day on the scraps tossed to him like a dog. It was only by his own merit he made a life at all. Never in his life did he ever think he'd wake up in prison, esspecialy for crimes he never committed!
When the gaurds called him a heretic or witch he didn't know what they ment. Him? A heretic? Hardly... Sure he didn't believe in faith, but never had he been outspoken with it, or ever even try to turn others away from faith as well... To his own knowledge he was just a beggar, and these gaurds where just mistaken...
