Lore
Many millenia ago, when Terraria was anew, a curious energy anomaly had borne the Ancients deep underground from elemental crystals through an unholy ritual. Their very beings threatened Terraria when they emerged from the earth, as although they had terrifying combined power already, they suffered an insatiable appetite for power. During their odyssey for power, they confronted an omnipotent primordial being known only as Abraxis, who granted them incomprehensible power, but warned them of using the power against Terraria or there would be most severe consequences. A deal the Ancients could not resist.

The Ancients devised a plan out of Abraxis' sight to destroy Terraria, and unearthed a forbidden ritual that produced a hungering infection that sought to obliterate the universe and all of its life itself, planting the infection into a poor unsuspecting soul. When Abraxis found out not too long later, he was furious, robbing them of their vitality and sealing it away for eternity, its physical form only to come into fruition should several incomprehensibly powerful sources intersect.

The Ancients were left only as mere wisps of consciousness lost among an abyss, and so the wisest of the Ancients, Izaris, formulated a tactical plan. The Ancients crept from their hiding spot and, to avoid the wrath of Abraxis that would inevitably be the fall of them, warped together into the form of a meekly old Terrarian—the Storyteller—and they waited many moons until the young hero arrived. They then used the hero as a tool to slay the great primordial beasts of Terraria, alloting the Ancients each enough combined power to return to their physical forms, and additionally erasing much of the forces they failed to apprehend—and plenty more to eradicate the hero and seal the dark fate of Terraria forever, leaving them as the unquestionable gods of not only Terraria, but the universe itself, for eons until the stars died out and the universe came to a peaceful halt.
