The undead kings beginning

Richard have not had an easy life, although not a brutal one either. During his 12 years of life he was simply being neglected by his single father so it was a surprise for him when after his father got remarried that they would poison him on his birthday. Fortunately or unfortunately an evil God offered him to be resurrected in another world as an undead in the body of a discarded noble child. Obviously he agrees and now must learn to harness his new powers to survive.
