Origin Cave takes place in a universe known as FATE. This universe was conceived by Madison Trupp and is where most of her other creative works take place, too. Notably, Origin's lore revolves around radiations or beings known as the Fates. In total there are nine Fates, but not all of them are important to the lore as it pertains to the caves and some may never be discovered in this game!

Here's what we know so far:
— Rrevalk, the FATE of Disorder (or Chaos), originally created the caves as a Valkhound Nest.
— Utzotl, the FATE of Natural Order, later repurposed the nest (begin: Cycle 1).
— Dontacael, the FATE of Order, has infected the caves with his hivemind known as the Hive.
— Lord Dhracia, the FATE of Control, meddled with the original purpose of this nest for her own needs.
— Hume, the FATE of Autonomy (or Wisdom), lends her magic to the other Fates to give the gemstones life, including the condensed versions of their Fate Radiation.

Fate Radiation is essentially the "magic" that the Fate produces and is the essence of their existence. Their radiation can sometimes condense into their own stones or Spires, some of which can be found in the caves: Skystone (End, summoned by Utzotl), Oilstone (Rrevalk, Disorder), Clearstone (Dontacael, Order), and also the natural gemstones that are the sources of magic for the Gembounds. Rarely we may see mention of Hume's condensed radiation, Magnolet, but it does not occur naturally in the caves.

The numbers associated with the Fates are static and do not change, but are important. Origin Cave only has names for radiations associated with numbers 0, 1, 2, 3, 4 and 5. The list below ends at Hume (5) as the other names of radiations have yet to be discovered—and may never be discovered—in this pocket of the FATE universe. Be sure to explore the other works of Madison Trupp! (wink)

The Fates do not reside in the caves and are unlikely to make physical appearances but may still be mentioned in threads.

Fate Radiations 6, 7, 8, and 9 are a mystery to Origin Cave.
