Time is Ripe
After the day on which Jason had gained favor of the entire Celestia race had passed, years flew by before the day of the Tournament of the new Gods finally arrived.
He studied the various domains of the Celestia race, and got to know the differences between the more advanced and developed domains in comparison to newly manifested ones.
Keran's domain could be said to have reached a relatively high standard because his God's Halos enhanced the effects of his domain to the extent of a slightly more developed one.
This was something not many newly advanced Gods would be able to say about themselves.
With that in mind, Jason also learned the unique traits and advantages of the other Primordial races.
From this, it was possible to figure out where their domain was leading to.
One was not able to tell anything for sure, but roughly measuring it was already more than enough for Jason to feel much better.
