So, not including information from later in my lore event...
In the beginning there were two crystals, creation and destruction. Eventually they created the first universe
A being known as the creator found the crystal of creation, and Mr. Void found destruction.
Stuff happened, eventually they fought, and void lost the battle. Losing his crystal in the process.
But victory came at a cost. Creator was losing his physical form.
So in his last moments he sent the crystals far away into other universes, hoping they wouldn't fall into the wrong hands. He also told the banisher, his highest servant, to scatter powerful weapons across the newly made multiverse. Just in case void ever returns.
The crystal of creation landed with the collector, but destruction... Kinda went missing.
You can easily see where this is going.
