In the world of Terrarium, there are many Gods. The Four Original Gods were the ones that descended from the stars, the four of them created the twelve Chief Gods, given the task to maintain and nourish humanity, while adapting the new world they had discovered for the inhabitation of their race and creations. However, many more gods were born out of love between their creations, sometimes out of pure selfishness, as they required more servants to spread out their tasks. The twelve gods then created many subordinate gods, some were spirits which they allowed to ascend to divinity with their powers, and others were children between one another after a night of passion. , their creations also made more gods between one another, and many more gods were born.
Over the eons, the world of Terrarium had many gods overlooking from the heavens, although they were always unified together in a big pantheon, disputes, and differences between the twelve gods surged. Some argued against the other's ways of handling things, this created disapprovals, and sometimes, even hate between each other. This made it so they couldn't control their temper when somebody that always disagreed with them was present. The twelve gods separated then, creating twelve pantheons with several gods in each pantheon.
Each Pantheon represented each element that these twelve gods governed. The original four gods overlooked their creations, which they created specifically to protect humanity and their other creations and to "adapt" the world of Terrarium so their race and their creations would inhabit it. Gods could be said to be rogue entities, traveling from stars to stars, using their powers to bring life into other worlds. However, the four original gods saw in the world of Terrarium flourishing life without any godly intervention, quickly after, they realized this wondrous world with vegetation and life was… alive.
As travelers and conquerors, they set in motion the conquest of this living world, creating the twelve titans to oversee Terrarium and then the twelve created more gods to work for them, and then, humanity and the other races related to humans emerged spontaneously, spreading across the world and conquering it with their adaptability and amazing capabilities compared to other entities in this world, especially their great intellect and the ability to develop abilities that were not purely magic-based, Weapon Techniques, Physiques, and other supernatural powers were quickly developed. But as the bloodline of humanity became thinner over the generations, and their god given powers slowly dissipated, they grew weaker.
And the world of Terrarium decided to counterattack… that's when the first Demon King was born, and the Gods realized that the world wasn't going to let them do as they pleased. After the Demon King's war which even took the lives of several subordinate gods, the gods retreated into the skies, where the world's creations could not reach them.
But what about humanity? Humanity ended staying in the world's surface, populated by monsters and… demons, these two forces constantly attempted to overpower humanity and bring them to extinction. The Gods, fearful of the monsters and demons, and the rebirth of a new Demon King, they granted Blessings and power to their creations, and Heroes were born, representing each of the twelve gods, these powerful members of humanity and other related races unified humanity as a whole against the menace of Demons, who were advanced forms than monsters, as shared many qualities, but were intelligent and cunning.
And … history has repeated itself over many eons, over and over again. A Demon King rises, destroys, and is defeated. Humans become heroes, fight for what they believe, and die. The circle never ends…
The figure of a transparent entity floated amidst complete emptiness. It mildly resembled a human, but it was made out of transparent energy, shining with bright, cosmic light.
"What a disgusting cycle… Is this what the four gods wanted from this world?"
The figure looked into the world from below, the vast world of Terrarium.
"I failed my attempt at killing them… That Demon General proved to be incredibly weak at the end. What a disappointment."
In the world of Terrarium there were many Gods. Some gods served the great twelve, but others sometimes decided to be by themselves. Over time and many generations, these gods continued to increase in quantity, they were often called rogue gods. Some made themselves known by the world and the gods as enemies, growing selfish, and with a never-ending desire for power.
Others created their own religions and cults and tried to make humans pray to them, gaining power from their belief, but because they stranded from the original twelve, they were cursed for not serving their creators, and their appearances distorted to how their hearts truly were, becoming monstrous and demonic in nature and appearance… these were called Evil Gods.
Some of them even decided to ally the enemies of the gods, demons. They began to help demons fight humans, as demons were often desperate for power, and had no gods to pray to. Over thousands of years, these Evil Gods became famous figures in the Demon Continent, and gained unprecedented power from the beliefs of billions of demons, some had speculated that their power, from mere subordinate gods, could now rival the twelve.
And amongst all of them… one of such Evil Gods had the power to manipulate space. It was one of the oldest Evil Gods who stranded from the path of serving his masters. Distorted by his own beliefs of what peace truly was, he walked his own path and became a feared god when he created a pact with the world. He still could remember it, when he promised the world's will that he would do as he was asked in exchange for the power he received.
"I shall fill the world with dungeons and bring demise to humanity."
And since then, Dungeons began to emerge all across the world, corrupted miasma distorted space and time, creating ruins out of nowhere, with internal and vast spaces inside… This was the beginning of the Age of Dungeons and Labyrinths.
