He won.
Or so historians would like to say.
The reality is that he was betrayed by his companions, in collusion with the God of the World.
In the end, the most talented man in history was seriously wounded and had to flee far from his homeland.
At that time, the Southern Continent was forgotten and desolate. It was ruled mostly by amazing beasts, with settlements and the occasional human city seeking to subsist in this dangerous world. They succeeded, but the beasts on this side of the world were too powerful to cope.
Most people had to live in the shadows of the great beasts.
Though severely wounded, he cleared the Southern Continent from head to toe. Many of the beasts were wiped out by his hand.
He wanted revenge.
He wanted to build the greatest continent on his own. He wanted to build a continent that would allow him to stand up and support him when he went to challenge that bastard again.
But he failed.
No one knows why.
