HISTORY
(Mostly I copied from Its wikipedia Page so you know better and me dont needing go deeper into details because most of you know already this)

The franchise is loosely based on a set of New 52 storylines from the DC Universe. Following a teaser in the franchise's first film Justice League: The Flashpoint Paradox, a five-film story arc loosely based on the "Darkseid War" series written by Geoff Johns, started from Justice League: War and was later revisited in The Death of Superman, Reign of the Supermen and concluded in Justice League Dark: Apokolips War, the sequel to 2017's Justice League Dark. The franchise heavily focuses on Batman and his son Damian Wayne, the latter of whom becomes the new Robin in this continuity.

The franchise also includes four Batman and Justice League films: Son of Batman in 2014,[2] Batman vs. Robin in 2015,[3] Batman: Bad Blood in 2016,[4] and Batman: Hush in 2019,[5] Justice League: The Flashpoint Paradox, Justice League: War, Justice League: Throne of Atlantis and Justice League vs. Teen Titans, two Justice League Dark films: Justice League Dark in 2017 and Justice League Dark: Apokolips War in 2020, two Superman films: The Death of Superman and Reign of the Supermen and one Suicide Squad (Suicide Squad: Hell to Pay) one Teen Titans (Teen Titans: The Judas Contract) and one Wonder Woman: (Wonder Woman: Bloodlines).

Relation to Earth Prime

As you already know, this Earth is the Identical twin Earth of Earth Prime after all Flashpoint mess created by Flash and Zoom.

Now this Earth's time period lasted for 7 years (2013-2020) until Barry again needed to make another Flashpoint, but because he is the "Original" Barry who first made the Flashpoint on Earth Prime, he again created the mess.

Now because of this Flashpoint, Earth 1 will be stuck in the time loop of same events happening again and again, until an Crisis on Infinite Earths happens, so from Darkside invasion in 2013 to his defeat in 2020, but he already won.

But that wasn't the only thing this same Barry screwed up.

Alternative Earths

Earth 1 can be now know as the first Earth in the Darkoverse to start creating it's "Sub-Earths" like the sub-species in animals, this time in Earths.

As all these Earths originated from Earth 1, they can be divided into 2 categories:

1) Hoodverse

Earth ??, also know as Dark Love, is one of the Earths originating from Earth 1, which created it's own mini-verse called Hoodverse and it's Main Earth of the Hoodverse

So all Earths originating in the Hoodverse fully or DIRECTLY ORIGINATED FROM Earth "Dark Love" ?? and SEMI-ORIGINATED FROM Earth 1

Hoodverse:
Earth Dark Love [Main Earth]

Earth 11
Earth 13
Earth 18
Earth 20
Earth 24

NOTE: Because not all Earths in the Darkoverse are discovered, it remains to be seen how many more of these unknown Earths are also in the Hoodverse

2) Reflection and Not part of Hoodverse yet

The name says it all, Earths that originated Earth Dark Love but still are unknown or if they are known, they still arent yet fully established in the Hoodverse

NPH:
Earth 26

NPH =Not part of Hoodverse yet

But there are also Reflections, like Earth 17

Earth 17 has fully originated from Earth 1 and has no connections to Earth Dark Love, but the only minor connection Earth 17 and Earth Dark Love have is some same dialogue or action but with 2 different characters, one Earth each respectfuly

Reflection:
Earth 17
