So! Welcome to a very long winded way of saying that Ebony started everything. This will be broken up into parts. We'll start with an overall view of what OT!verse essentially is. So sit back and relax because this is a long one. Don't forget that you can always ask questions. So without further a do let's get started. Oh! also Disclamer: None of the fandoms mentioned are mine.
OT!Verse is the result of many broken timelines and an abundance of moon energy. After Ebony went to a previous timeline of where Phantom hasn't eaten the apple, to eat it out of stress, this was the catalyst of everything in OT!verse. Sense, he now had that corruption and had access of the Aus, you can see how this could cause issues. The other part of it is the amount of moon energy in the multi-verse and not enough sun energy.
This as you can tell would later cause a mess of broken timelines and Aus. However, this would cause the multi-verse to be unstable. Hence Stardust being born/made into the multi-verse to stabalize it. Now we'll get into roles with the multi-verse later because I'm writing this at 11:10pm where I am TnT. Anyways, that's the overview so far. Now I'm going to suffer with the lore and world building.
