Welcome to the world of the Jelvia!
Jelvia: Not Human
Just for a minute, imagine Earth becoming invaded by a higher intelligence from outer space. Of course, our defence would result in overdrive to protect its inhabitants from the threat. In fact, it’d probably destroy the threat before it got even close!
So, those ‘higher beings’, being higher and all that, would know that, surely? So wouldn’t it make sense that they arrive with some sort of disguise? Or even alter our memories of them coming?
Welcome to the alternative world of Jelvia: Not Human, where humans and Jelvias coincide.
It’s going to be bitter-sweet carnage.
