The life of the boy who had suffered several years with this affliction had come to end with little time for him to despair as he died without an attendant by his side. When he awoke again, he had been made into the lowest ranked undead by an evil necromancer. Though the boy rejoiced at having obtained a body that could not feel pain, he immediately realized that he was still at the mercy of others. There was no large difference between his present situation and being confined in bed. However, because the boy wished for peace, he couldn't leave the world as it was.
