Stranger Things season 4 volume 1 finally reveals the origin of the Upside Down, showing the moment when Eleven created the first Gate.

The mysterious realm known as the Upside Down is the key to Stranger Things, a twisted version of Hawkins that is home to monstrous beings such as the Mind-Flayer and the Demogorgon.

The origin of the Upside Down has long been something of a mystery - but, given Stranger Things season 4 is marketed as "the beginning of the end,"

Stranger Things: Kamchatka miniseries by Michael Moreci, Todor Hristov, Dan Jackson, and Nate Piekos, released ahead of season 4 as an official tie-in.

This introduces readers to Russia's version of Dr. Brenner, Dr. Boris Orlov, whose theories appear to be directly related to the creation of the Upside Down.

Like Brenner, he has been conducting experiments in telekinesis; significantly, he believes this power can serve to open doorways to "infinite worlds."

This may well hint at Number One's plan in Stranger Things season 4's present day. The Gates he is opening may well serve to draw the dimensions even closer together

it is conserving its forces for the merging. If this is indeed the case, Stranger Things season 4 volume 2 will see matters escalate even more.
