Primalism

Basics:
Enderiua created the End and Ryvaos created the Nether. They worked together to create the overworld. The religion states that there are two planes of existence. The Mortal Plane, which we exist on, and the Ethereal Mirror where the gods, mythical beings, and the dead roam. The Ethereal Mirror is a perfect mirror of the Mortal Plane, but the two never connect. Buildings on the Mortal Plane appear on the Ethereal Mirror, but buildings on the Ethereal Mirror will never be viewed by the Mortal Plane. The gods have guidelines and depending on how well you follow the guidelines, when you die you will either be granted access to the Ethereal Plane or be cast into the depths of the void for eternity where you will find no air to scream and no energy to leave.

Minions:
The gods both have minions to travel the Ethereal Plane and even occasionally the Mortal Plane for them.


 * Enderiua has Watchers. Tall humanoids with purple cloaks, dragon wings, and faces that consist of an incomprehensible amount of eyes. They see everything and everyone and they watch from their obsidian towers they build. Only three Watchers will exist at a given time. If one were to die, the others would go into recruitment. Searching for brave and valiant heroes to bring into their ranks.
 * Ryvaos has Brines. They look to be humans with glowing eyes and they can control the earth as their magic. Implanted in their heads are shards of Lapis Lazuli. They are not as powerful as the Watchers, but are more numerous. For recruitment they will steal children from the Mortal Plane to raise as Brines in the Ethereal Plane. They reside in nether-brick pyramids and are said to convince Piglin to do their services.
