Regnorumism

Regnorumism is the belief that the four realms, Overworld, Nether, Void, and End, are all safeguarded by Gods. The belief's origins can be traced back to the first appearance of the Goddess Luolis in Rathnir, 1412 AC while the religion originated from Denakrain2 in Grogonia. This religion stems from the idea that there are untold numbers of Gods watching over the mortal realm, caring for us all. They protect the realms from Morumbra, God of death, darkness and the void, against his thirst for extermination.

Existence
At the beginning of existence, 4 realms were created. The Overworld, the Nether, the End, and the Void. These 4 realms were all perfect havens, hosting life in all forms. During the creation of the realms, many beings were created to sustain these lands, they were dubbed “Gods”.

Soon after, their ideals and beliefs clashed, causing fights and arguments between these great beings. Morumbra, God of Death, Darkness, and the Void, grew tired of the petty squabbles and killed many of the Gods within the Void. Panic, confusion, and fear corrupted the 4 realms, only a few Gods were capable of keeping their heads up during this period. While Morumbra continued their slaughter these few beings formed a guild of Gods capable of fighting it back. Other guilds like this were formed but were crushed without hesitation. The only other guild to survive this period would be filled with the ruthless murderers.

This massacre continued on for millennia, only stopping when they received a deadly injury to their arms. Incapable of killing anymore, the guild occupying the Void captured and tortured it for the rest of time. This period would be known as The Great Massacre of Morumbra

Collapse
After the Great Massacre of Morumbra, many of the realms lacked the gods required to keep their ecosystems stable. Mainly the Void and the End. The Gods within these realms know this and chose to escape to the remaining 2 realms, leaving the few remaining mortals to die. The Nether and the End, once filled with forests as tall as the sky and rivers as clear as glass, crumbled into unlivable hellscapes. The Nether’s ecosystem burned, flooded with lava, and became populated with pig mutants. The End collapsed into the Void, merging the two realms together.

The gods retreating were seen as cowards and stains on their society. They were banished to the End, left to die for their crimes. The Gods remaining in the Overworld not yet in the existing guild joined them in order to prevent the total collapse of their realm. This succeeded, leading to the prosperity of the Overworld and the eventual appearance of the humans.

Resurgence
With the appearance of humanity came true intelligence within the mortal realms. These creatures used tools and hunted in groups, communicated and built societies. Humans became a great interest within a few of the gods, leading them to make contact with these mortals.

The first time a god descended to the mortals was in 1412 AC (After Collapse). They were known as Luolis, the Goddess of Light and the Sun. The moment she stepped foot in the Overworld, she began to preach to the locals about her experiences. Although the Gods were incredibly popular with the populace, a religion was never truly created. Only the ideals were carried through time

Beliefs and Philosophy
Regnorumism is the belief that the four realms, Overworld, Nether, Void, and End, are controlled by 2 guilds of Gods. After the massacre, collapse of the Nether, and the merge of the Void and End, the Gods fell into chaos. An unknown group of gods had built up their numbers, later inviting Luolis and Amatuere to their ranks. Although this group has no official name, it is often referred as "The Guild" or "Sky" by their followers.

In order to recieve as much of Amatuere's Blessing as possible, followers of Regnorumism build their homes incredibly high, piercing the heavens itself. This is also done as a sign of respect for the kindness they have given Rathnir over time, therefore moving closer to him, his sister, and the Gods affiliated with him while also moving further from the captors of Morumbra, and their bad omens.

Luolis
The symbol of the gods. Luolis is the only known goddess to make an effort to contact the mortals. Her brother, Amatuere, does help, however he believes meddling in the mortal’s issues is a waste of their time. Luolis is a kind, compassionate person willing to help anyone in need of her assistance. She makes it her life goal to give the mortals a peaceful life, while also studying them to see how they behave in certain situations. She is depicted as the sun, giving her warmth to all those who bask in it while also lighting up the night through the moon to ease fears of the dark.

Amatuere
The protector of the Overworld. Amatuere will grant his blessing to those partaking in dangerous activities only when his sister forces him to. He fought, and won, against Ardenis, trapping them in the Nether to prevent them from bothering him again, he bares a burn scar on his upper torso from this fight. He is depicted by most humans as a gladiator wielding a gladius on both hands, while also carrying a long bow on his back.

Morumbra
Death. It has been the leading entity in the battle against all Gods. The deaths of multiple gods, Void or Sky, have been confirmed to be killed by it. They are a ruthless, merciless being with the sole purpose of bringing destruction. There are no depictions of Morumbra as it's said it will bring death to you and your bloodline for marking his "perfection".

Ardenis
The symbol of the Nether. They are a spiteful being, sending hordes of pigmen, ghasts and other mobs to toy with mortals. After being locked in the Nether after a battle with Amatuere, they developed an insatiable thirst for revenge against him, unable to act on it due to their limited range. When playing with mortals, they appear as a group of rocks and magma in a humanoid shape.
