The other spirits were easily deceived by Exnor as Exnor blamed the Gods for the banishment. The Gods afraid of the spirits would somehow become powerful from Gods and that's the reason why they got banished as well.
Some of the spirits did believe and some of them were not... but almost half of the spirits joined the Exnor cause and with that, a legion of undead was born. Which disturbed the peace of the World of Arenia.
Mortals couldn't fight back the undead as they don't possess the divinity to repel them. So as time passed, many mortals began to die in the fight against them. Only a handful of them remain but all of them had lost hope as they knew their chance at winning against the undead was zero.
As the world was plunged into more chaos, the Gods in the heavenly plane did nothing as they didn't care about the mortal world at all.
Auslosha on the other hand was beginning to fade as she didn't want to possess a body and saw the World of Arenia was collapsing by Exnor. Auslosha knew that she had to step in... to prevent the destruction of the mortal world but what could she do as she had no power to stop Exnor.
But it seems like fate has brought someone willing to become the vessel of Auslosha. A young girl called Arnia came across Auslosha in the forest one day. As Arnia was getting chased by the undead at that time around.
Auslosha on her mortal form then repels the undead from harming the young girl using the remaining power she had left. Because it was the weak undead, they were immediately killed by that presence alone.
Arnia, who saw everything, was astonished by Auslosha's power... the young girl begs Auslosha to save her family from the undead but sadly Auslosha rejects it. The reason was that Auslosha had used all of her power to save the girl from that undead before.
Auslosha also explains to the girl that she would soon vanish from the mortal world...
Despite hearing all of that, the young girl begs and is willing to do anything to save her family. Seeing the girl's dedication, Auslosha shares the only way for her to keep existing in the world and also for her to be able to save the young girl's family.
Without giving much thought, the girl agrees right away as it was the only way for her family to be safe. Auslosha did ask again whether she was sure of her decision and told Arnia that once the merge happens, Auslosha explains that she would be using Arnia's body to stop the undead and so she couldn't be there to protect her family.
Hearing that, Arnia nodded in agreement. But before the merge, Arnia told Auslosha where her family was... for Auslosha to be able to save her family.
Thus Auslosha merges with the young girl and prolongs her existence in the world. With a psychical body, Auslosha could feel her power was restored once again and to fulfill the promise she had with Arnia.
Auslosha went straight ahead and saved her family but after it was done. She soon leaves them to stop the destruction that Exnor had caused in the world.
But Auslosha knows that she alone couldn't save the world, so with that Auslosha decided to gather the rest of the spirits that didn't join Exnor in the first place.
Yet the task wasn't easy as not all of the spirits were easy to convince off but because of Auslosha's determination into saving the world, the other spirits agreed to do it but just like Auslosha... they needed a vessel as well to fight against Exnor.
With that Auslosha finds any mortal that's willing to be giving their body to the spirits. Surprisingly, many mortals sign up with the cause as they hate being able to do nothing when someone their love is being killed right in front of them.
So many mortals merge with the spirits thus making a new kind of mortal... one that merges with the Spirits of Beast had become a beast-man. Spirits of Magic had become a mortal that could use magic, known as mages and wizards.
The rest of the mortals that didn't merge with the spirits were also joining the fight but they're granted the blessings of Auslosha to repel the undead and be able to kill them off.
...
The fight between the Exnor faction and Auslosha faction was quite the battle, as it lasted for almost hundreds of years but in the end. Auslosha finally managed to defeat Exnor and maintain the peace of the world.
But not all of the undead were defeated as many of them scattered away when Exnor was defeated by Auslosha. So in order to keep protecting the world from the undead threat.
The Beast King, The Grand Wizard, and God Auslosha had agreed that each of them would be living in the three different continents in the World of Arenia with their followers and purge the remaining undead in the world.
...
Humans learn that Auslosha originally came from the God Realm. The humans began to devote themselves to Auslosha and created Auslosha Faith at that time around. All was to spread the glory and the teachings of Auslosha.
All of this because only Auslosha is the one that had to save the world from the destruction and none of the other gods even care for the mortals when they're in trouble.
At first, Auslosha rejects the idea but as she knew that she would eventually perish soon enough, as it was the effect of the constant use of the divinity power Auslosha held in her mortal body. She decided that it might be good to just let it be as the teachings weren't evil at all.
When God Auslosha finally perishes in the world, the humans are sad but they know life must go on... The only thing the human could do now was just to spread what was left behind of the Great God Auslosha.
