Religion

Religion differs from the religion we know. Unlike the people of Earth who worship deities and argue about with gods are real and fake, most of the universe already believes the two great deities of the universe, the Great Dragon and the Great Phoenix. The two deities are undisputable, everyone knows these two beings exist and though there's disagreement about some theories about the two everyone knows the general story, there's no denying. However the problem is that after the Great Battle the two being became inactive and slumbered, so the two gods don't really do much though some theories suggest that all fights and conflicts in the universe from the Great Battle to present day are because the Great Dragon and Great Phoenix indirectly battle with each other using events and people as pawns. But even then the two real gods of the universe aren't really that active so there really isn't a religion between the two gods. Though throughout history instead powerful beings existed to quench the many different peoples wish for a being that would protect them, that will guide them, and basically be a notion for religion.

Powerful Beings
Religion in the universe are mostly based on a powerful being rather than an actual god or deity. Throughout many civilizations and worlds powerful beings of all kinds of species took the role of being a worshiped figure in their civilizations. These powerful beings were way more powerful in their powers and magic than many in their respective civilization and communities. Much of those beings also had the rare gift of being immortal, immortal in the sense that they can't age, only way for them to die is to get killed.
