After the Light Primogenitor joined the experiment, they found out that it was instant death to anyone going for multiple perfect manipulations.
The worst part? The moment that descendent died, both the light and Gems elemental manipulations were forever lost!
They weren't bestowed to another and died with the owner! They didn't even return to the original primogenitors.
Till this point in time, there was no presence of an individual with either of those perfect manipulations.
With those disheartening results, the gathering was concluded, leaving every primogenitor more depressed than ever.
That's because they firmly believed that for the perfect elemental manipulations to be completely lost only meant that the universe found that their existence didn't matter much to the grand scheme of things.
