Necromancer Carrying a Coffin

The former Holy Knight, the pride of the bright world, in this almost perfect world full of light and happiness. A story of descent into darkness and struggle. How does a necromancer struggle for hope in a bright world? How can a person who has lost a loved one find the motivation to survive on a lonely journey? The writing style tends to be traditional and I don't like water injection. This is a story about faith and the world.
