The Storm That Shifted Time
History
A great storm raged through the Time Dimension a hundred billion years ago, disrupting the flow of time. Typically, time flows in one direction at one speed, but the storm caused the liquid to flow in all directions. Since the Time Dimension acts as a spirit dimension, i.e. it cannot by physically accessed but it overlaps with other dimensions, nobody knew about this storm, but there were tangible effects.
The change in the flow of time dragged things from the past and future to the present. This most notably included planets, solar systems, galaxies, and worst of all, black holes. As time went on, as best as it could, things were dragged from farther in the past and farther in the future. Entire civilisations, primitive beyond one's imaginations, were forced to compete with the present sophonts, and cultures so far into the future, with science and magic skills infinitely more complex than the present day, were able to claim much of the Yonderverse as their own.
The effects lasted thousands of years (or maybe just a few minutes, nobody knows), until the fabled Time Soldiers arrived on scene. This mythical fleet of soldiers exist in the Time Dimension, and manage any altered flows of time. Nothing as big as this storm had ever been seen before, which is why it took so long to fix.
When the storm's effects had been reversed, present day returned to normal. Unfortunately, the Time Soldiers cannot alter people's memories, so the traumatic events still lived in people's minds, manifesting into myths and legends that still live on today.
Cultural Impact
If you ask someone what the worst disaster in the history of the Yonderverse was, they'd probably say the Storm that Shifted Time. Or the time when sliced bread was banned in the Milky Way, those were dark times. Everybody in space knows about this event; artworks depicting this disaster are plastered in every historical building in the cosmos.
Everae Rule
During the aftermath of the Storm, the planet Everae crashed into present day from the far-away future. These people were advanced enough to know about the Time Dimension, and so when they found their way into present day it did not take them long to figure out what had happened.
The everaeans were incredibly powerful people, with even the lowest class citizens having the power to wipe out entire galaxies with just a thought. Their technologies were so complex that nobody in the current present day have the capacity to comprehend their inner workings, and these people believed in an oppressive society.
The everaeans were quick to take control of the Yonderverse in their new time period, forcing those beneath them into labour, which just so happened to be every single person in the Yonderverse. To control people they threatened to wipe out planets, solar systems, and galaxies, and they even vaporised a few to show they meant business. For as long as it took the Time Soldiers to reverse the effects of the Storm, these people ruled the Yonderverse.
I love the idea that this event is the source of a lot of myths and legends in the Yonderverse. Sounds rather horrifying. Also nooooo, not the sliced bread!
Thank youu! My world needs more horrifying stuff >:)
