After years of war, the different races finally live in peace, prosperity and happiness... except, the race of the undead, they don't count, after all, they were the losers.
And as losers, their fate was sealed: marginalized beings, condemned to slavery and banished to inhospitable wastelands. The same as every day.
The heroes received fame and fortune for destroying the demon god and Lyon, well, he is in good health at least.
Being secretly excluded for having black magic very similar to demons, he was soon forgotten by everyone. And as if that wasn't enough, he was betrayed by his friends in the end.
"I'm sorry, your presence makes us all nervous" with some excuse they threw him into the abyss of the dead.
What they didn't expect was that Lyon would awaken a unique stigma: tame death and take control of your destiny.
