An artifact is an object made by a being, typically one of cultural or historical interest. Artifacts are ancient and lost items that can date back to the previous beginnings of world cycles.
World Cycle is the period of time in which reality takes place, new histories and new stories are made in every world cycle.
The gears of fate begin to move when an old-world cycle comes to an end, that's how a new world cycle begins.
Heroes, Villains, Protagonists, Treasures, a whole new history is made.
A weapon is a thing designed or used for inflicting bodily harm or physical damage.
While Treasures are precious, valuable objects that the world itself gives birth to, no species can ever make a treasure.
Artifacts, Weapons, and Treasures are sorted into nine tiers.
