Editing Demiplane of Dread (section)

==Cyre?==
In [[Eberron]], the nation of Cyre was destroyed in the Day of Mourning, leaving only the [[Mournland]] behind. That Cyre became a Demiplane of Dread is perhaps the most common theory on the origin of the Mournland within the fandom, as it checks all the boxes for explanations.
*The Mournland stops at Cyre’s artificial, political, borders and thus had to be caused by some intelligent actor. The Dark Powers certainly count. It also explains why it stops so exactly at the water that the docks were left behind.
*The Mournland’s border is a wall of “dead-gray mist”. The link is obvious. In 4th Edition, this dead-gray mist supernaturally drains people of hope.
*The Forge of War states that Dannel ir'Wynarn insistence that the crown of Galifar belonged to her was the only thing keeping the Last War going, making her prime Darklord material.
*Dark Sun material describes Kalidnay as having been destroyed by "unknown disaster" that left it only "a jumble of ruins". The ruins in the Mournland are described being "moved", "rearranged", "turned 90 degrees", or "found miles from where war-era maps say they should be", which certainly can be described as a "jumble". The one adventure that travels to the ruined city (DSM2) mentions several structures remain intact, and many appear to be ruins purely because they're centuries old, which fits the multiple Mournland adventures with surviving structures, and several people seem to have died suddenly in a way that their body was intact. (While some of the Mournland's signature features are absent, all outside descriptions of Kalidnay are centuries after the fact while all descriptions of the Mournland are 0-4 years after its creation.)

None of this will ever be confirmed, and it’s unlikely to be anti-confirmed, as the truth of the Mourning is one of Eberron’s mysteries that exists to have no answer but what the [[Dungeon Master]] gives them. The setting's creator has however concurred it's a good option if one wanted some bit of Eberron in Ravenloft.

The theory received a bit of a nod in 5th edition with the reveal of a new Domain of Dread that is a fragment of Cyre that was taken by the mists on the Day of Mourning. Keith Baker also later released a supplement called [[Dread Metrol]] which makes the capital of Cyre another Domain of Dread.
