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.
