God of mirror, vortex, wolves, spear

When the giant race was trying to invade this world, around 30,000 years ago. The gods were yet to create the barrier around the world's core. 

Their mobility was not restricted at the time. 

No matter how strong the Giant hero was, he was not capable of creating a seal to stop the red portal. 

The gods were the ones who manipulated him from the shadows, leading him by the nose. 

Mostly it was thanks to the gods that Fuiren, the giant hero, experienced one enlightenment after another. Not facing many blocks in his research for a method to take care of the portal. 

The red portal was a mysterious thing, it originated from another world, but it was strangely connected to this world with its own world core. 

This red portal was so deeply connected to the world core, that destroying would be no different than destroying the world core. 

This was what bewildered the gods most, making them plan to seal it.
