There were many spiritual beings in The Great Thousand World, among which numbered several Spiritual Beasts. As Spiritual Beasts usually possessed great talents, they generally had longer lifespans. This trait enabled them to build a strong lineage, which caused many of the human beings to be wary of them.
The Spiritual Beasts also had the most complicated bloodline among all of the spiritual beings in the Great Thousand World. Moreover, since their bloodline was the source of their power, the clan with the most powerful bloodline was known as the Divine Beasts Clan. Those from the Divine Beasts Clan were born with great powers, which caused everyone to fear them.
Yet, there were still a choice few, who were not of the Divine Beasts Clan. This was because they possessed the same latent abilities as the Divine Beasts Clan. One such example was the Nine Netherbird Clan.
