From Paladin to Demon Lord: Betrayed by the God of Light A Litrpg [Completed]

All Ivan had ever wanted was to heal the sick, maybe travel the world, and make a home like he had growing up with his childhood friend and promised love Tanya.  All that is stolen away as the God of Light, Theadus, receives a prophecy from a minor Deity who calls itself simply The Oracle, and turns his armies upon a fellow God of his own pantheon to prevent his own downfall as foretold by strange foreign Goddess.  The story follows the tragedy of Ivan's life as he throws away morality and humanity to gain the power and magic needed to defeat the Hero of Light, and the long standing leaders of the God of Light's religion.  (Second book is up, please check it out :] )
