A Calamitous Dungeon

Lore

(Hello, to new readers that are somehow interested to this. If you are a player and is expecting the new lore, well too bad since this was created before the new lore was introduced. So I'm going to use the old lore still with a few bits of headcannon which is easier than rewriting the entire story.)

Tragic Origins

A billion years ago, Goozma created the universe along with a race of Light Gods and a race of Dark Gods, so they can manage the universe on its behalf. The Light Gods were obsessed with order, hierarchy, creation, and balance. The Dark Gods, on the other hand, were obsessed with chaos, anarchy, destruction, and war.

Eventually, the Dark Gods became tired of the Light Gods and their balance of the universe, and decided to declare war against them. The Light Gods, in their ever-present desire for order, smoothly declined the idea of conflict.

The Dark Gods were furious, and so to become more powerful for the upcoming war, the Dark Gods fused into a greater being, with Noxus becoming the main consciousness by force, with them being both the first and most powerful. Noxus, even more powerful than its creator, slew Goozma and began going to war against the Light Gods to wipe out their kind from the universe.

It was a close battle between Noxus and the Light Gods, with Noxus killing each Light God one by one while also taking serious damage. Amidst the chaos, a group of Light Gods fled to a planet called Terraria, so two of the Dark Gods, Cthulhu and Moon Lord, decided to split from Noxus and chase them while the rest of the other Light Gods and Noxus fought.

Shortly after, the Light Gods one by one fled to Terraria to form Xeroc, a being that would hopefully end the Dark Gods as a last resort. The combined presence of the Light Gods was powerful enough to deter Cthulhu and Moon Lord, who then retreated to the moon.

Noxus, after eradicating the rest of the Light Gods, cannot fight Xeroc in its current state, so Noxus started its goal of corrupting and gaining power across the universe, which resulted in the Astral Infection forming in its wake.

Unlike the Light Gods, who prefer not to act on much in the universe, the Dark Gods chose to stir chaos across the universe, squashing anything with the potential to become powerful enough to threaten them.

After gaining enough power to finally destroy Xeroc, Noxus was contacted by Cthulhu and Moon Lord for help, but they went to Terraria to instead punish them for their failure. Cthulhu was the first to fall, with Noxus firing a destructive laser that completely demolished it, with only his flesh remaining.

This eventually formed into the Crimson over time. Moon Lord was defeated soon after, with his bottom half sliced off and rotted over time, forming the Corruption. What was left of him was weakened and sealed inside of Terraria's moon.

Now setting its eyes toward Xeroc, Noxus completely obliterated Xeroc in a raging barrage of dark energy. With nothing left but its essence left behind, Noxus infused it into the land of Terraria as a means to prevent its influence from spreading throughout the universe.

Noxus, believing Terraria to no longer be of great significance, left to continue corrupting other planets. Unbeknownst to Noxus, Xeroc's will of creation allowed sentient life to be born in the land. Xeroc's lifeforce will periodically expand throughout the air in an attempt to form again, with the Blood Moon happening as a result of it.
