"I can't let this place die out…" Derik muttered as he kept releasing his aura which carried his soul imprint.
Ever since Demos died, the land was first chaotic since there was no one present to lead the beasts of the underworld. This continued for over a thousand years and after that, all the inhabitants of the underworld could feel the power maintaining this realm crumbling. If the realm should crumble, it simply means they will be destroyed alongside it.
So when they sensed the presence of a new master willing to save them from their deadly fate, these magic beasts couldn't help but be joyous and grateful. No one wished to know who or what saved them, all they knew was that the person who saved them must possess abilities similar to that of Demos and that's the only reason the domain was willing to accept him.
