First, Orsted.
He is from the ancient dragon-tribe, who came from an immemorial past to the present by using the method of reincarnation.
His body was harboring a curse and an ancient technique.
The curse was to be shunned by all living creatures in this world.
The ancient technique caused magic to recover at a slow rate, but in return it is possible to escape from Human God's sight as well as obtaining the ability to roughly see the future.
Why was such a curse brought to the present.
Because it was caused by the death of the first generation Dragon God at the hands of Human God.
Starting from the second generation, the reason for existence for all subsequent Dragon Gods is to defeat Human God, which was also the ancient dragon-tribe's dearest wish.
Thus the son of the first generation Dragon God, Orsted, was trying to defeat Human God.
