Upside Down, I have heard of this. I hope to never go there.
The multiverse is already a confusing concept. Now, couple that with the concept of parallel realities? Your hurting mind now roars in a throbbing migraine at the thought. But, believe me, such things are fact. Many can attest that traveling through time is just the creation or accessing of a different reality.
Author’s Note: Oh boy, here’s a complicated concept I’ve been eager to tackle. Also, here’s a chance to pay homage to various What If articles/adventures as well as fan-created takes on settings and lore. Also, what if The Grand Conjunction succeeded? Strahd and Azalin aren’t even the worst of it! And, save for one published article or concept; all these make homage to some work of sci-fi or horror.
They shouldn’t have existed, mistakes of nature and mistakes of humanity! These abominations were the accidents as a result of careless experiments and deadly warfare. And the result? Worse than we could have ever feared. Confused, angry, resentful, hateful! These things seek to destroy both their creators and the world around them. Much like the forces that spawned them, destruction is usually their goal. But, these creatures are no villains, but the consequences of arrogance, apathy, discrimination and violence.
Author’s Note: As a continuation of my theme, here’s a plethora of horrible mutants and mad experiments. While much of it is revisiting old monsters, there’s a good amount of new goodies to toss into your wastelands, super secret labs and other such locations.
