Excerpt from the Sacralibor (Mortideanist Holy Book), the Book of Relanarius:
Towards the end of the Ignorant Age, the prophet Relanarius was a born a slave. He was sold to a rich man, by the name of Grumio. As a slave, Relanarius started doing the hard work around the house, but eventually Grumio took a liking to him, and started giving him the easier work. Eventually, Grumio put Relanarius on his Will as one of the slaves to be freed. And for that insight, Grumio is a Saint.
As all things must, Grumio died tragically when Relanarius was in his thirties. Some say that the cause of death was a broken heart over Poppaea, his one true love. Whatever the case, Relanarius was free from slavery. And once on the streets, he had his vision, granted to him by his Pos'eity
"Relanarius," whispered the then unknown god. "Listen to me. Leave this city and climb the mountain that lies thirty-three miles north of here. There I shall speak with you, and reveal many things. Go, my chosen one."
The rest of the story features the Great Prophet Relanarius leaving the city of Muramor, and heading to the mountain. Upon arrival, he discovered the fact that the described mountain does not exist, and that the town that was 32.5 miles north of Muramor had never heard of a mountain existing there, and thought that Relanarius was insane. Relanarius therefore prayed for three days straight, looked up, and saw the mountain. And so he climbed it. And after a total of thirty-three days, returned with the creed of the religion Mortideanism.
The Cycle of Life begins with the animus. Some call it the spirit, some call it a soul, some call it a ghost, but the original Mortideanistic texts use spirit, as does the official church. This spirit floats around in the Priorterra. What exactly occurs in the Priorterra is a mystery that is not dwelled on much by Theologians- the point of life is to move forward, not backward.
The current part of life is known as the Apodyterium. When the mother and the father reproduce and create a child, all they do is make the "clothes" for an animus. And during its time spent in the womb, an animus will be transported from the Priorterra into the fetus. Some believe that this occurs when the fetus begins kicking, others claim before that, and still others say it occurs as late as birth.
Then the resulting human grows up, reproduces, and dies. At the exact moment of death, the animus leaves the body. But instead of simply being an animus, it has gained experiences. It has known joy and sorrow, love and hate, virtue and ignominy. They were like a chunk of clay in Priorterra, and their time as a human has twisted that clay, folded that clay, manipulated that clay, and turned it into a pot. The exact form of the pot depends on the way it was manipulated. Thus, it has ascended.
The resulting form is the god form, the last form. It is the ultimate legacy of a person. The sum of your experiences, the reasoning behind your choices, all decide on what the resulting god will be like. Deathbed conversions to virtue and honor do mean something. They affect the resulting god just as much as what you loved your life like for the 20 years before the deathbed conversion.
The gods then go to the Aeternus. There, they gain powers according to what suits them the most. The degree of the power is also according to how well, how "good-ly" they lived their life. They then do the things they want to.
An important aspect of gods is that they are immortal. They simply cannot die. Thus, they have no ending. And logic presents the fact that only things with no beginning have no ending. It is common sense. If it has a beginning, it has an end. If it has an end, it has a beginning. Thus, if a god has no end, it must have no beginning. Thus, they are eternal and existed before the person was born.
This is important because it means that praying to yourself makes complete and utter sense. After all, with the entire pantheon of gods up there to pray to, a person is more willing to pray to a god that will listen, and respons favorably. And who is more likely to listen than yourself? Thus, it is a common practice to pray to your god-self. Asking about life choices is a common one. After all, hindsight has perfect vision, and your god-self has all ready lived the thing you are going through.
Most people don't think about how not living your life according to how your future god-self loved it affects the god-self. It's easier that way.
A major controversy in the Sacralibor (the holy book) is that race is not mentioned. Some have taken this to mean that god-hood awaits only humans. In short, that the rest of the species are inferior and are acceptable to wipe out, kill, and be d**ks to. In short, be racist (speciesist?) to. Not all Mortadeanists hate other races, but most other people are ignorant of this fact and assume they are all racist.
Mortideanism is a full-on religion. All religious words are based off Latin. It takes a base society something like Rome (Muramor is Romarum backward, and means 'of Rome').
