Just this small group alone had enough gods to be respected by the Pantheon within the four hemispheres. In fact, if it was not because of their unique way of conquest, they'd be the second Pantheon, commanding the East hemisphere.
And, there was probably a senior god who ruled such a group. If, by chance, he defeated this tribe, what if another, much bigger one invaded? Or the senior true god came down himself?
It had to be said that the seniors had been here for at least thirty years. They probably had huge amounts of faith power, military might and influence within the world.
Though the previous generation could not compare to this one, they still had a fifty year gap between each other. A great headstart compared to this generation.
Even the weakest senior turned out to be a perfect true god, some being a ascendency true gods close to main true godhood.
