A word used by many. A law that holds a world together and promotes growth. An excuse. Whatever your opinion may be, Fate doesn't care. When your string snaps she'll laugh all the same. You need strength and destiny to even think of escaping. And even then all you do is loosen the strings that bind you.
As the wheels of life and death turn, as the gods wage war across their domains, as demons and abominations flee from Tartarus, the Sisters sit and weave something so great yet so terrible. Never ending. The tapestry known as Fate. The decider of mortals, reincarnation, boons for gods and Heroes alike, the luck of a world, the fate of a species, the beginning to the end of days. All things very important. Things that have been controlled by what the gods deem fair. Imagine how terrified the gods would be if this power lay in the hands of an enemy. The gods were terrified of the Sisters and so imposed a law that they can't see or manipulate their own fate in fear of the sisters using their strings to gain power. In their cowardice they never thought that leaving the Sisters weak would lead them to be targeted.
Today the weaver changes. A new Era begins spearheaded by the usurper - Arachne. An era where mortals, beasts, and even trees fiend for Ichor. An era wheee godhood can be stolen, where power is everywhere, and where even gods hide.
The day the gods lost their Wisdom. The first to fall from grace - Athena.
Surprisingly in the next few centuries many major events happened. The gods closed up their domains. Mortals experienced an influx of mana into their many worlds. And the gap between the Universes started closing. Devils from the Abyss started ending up in Hades. War heroes and fallen Demigods found themselves lost in layers who knows how deep. The abyss is a place so vile that even Tartarus was made to look like a child's toy. Even the world tree commenced an invasion on other realms planting its roots in worlds whose fates are uncertain. For even a weaver can't control all. Who knows if even the usurper is a puppet. Even Angels roam about collecting faith to use against their Creator. Ambition and Strength are all that will matter soon. As positions get claimed and new forms of power are created what will the Realms look like in a couple million years?
