In this AU universe, several things have been switched.

To start, there exists a chain that had been formed from the remains of a vessel of a Baskerville Lady: Demios Baskerville. This chain is known throughout the Abyss as the Queen of Hearts.

The Queen of Hearts would eventually, after being sent to roam the Abyss for decades, contract the mother of a boy named Leo illegally. After she died from a bullet sent by Pandora, the Queen of Hearts soon contracted the son. As mentioned before, things are different in this timeline. Here, Elliot Nightray was the one destined to inherit the name Baskerville Lord, with Leo cursed to carry the parasite that drained his life with each tick of a branded incuse.

Eventually, after Leo had slain most of the Nightray family in a series of events known as the Head Hunter murders (Vincent, being contracted to Humpty Dumpty, hadn't yet been discovered.), the incuse was completed, and then Leo and the Queen of Hearts were pulled down to the very center of the Abyss.

They met the Will.

It didn't take long for Leo to truly lose his mind, body, and humanity to the Abyss. The Queen watched as Leo was ripped apart and fused back together through the Abyss's influence with a new identity-- the King of Hearts.

Present canon: the King and his Queen rule in their own little section of the Abyss, picking off and devouring weaker chains, awaiting a chance when the Abyss will open up and a contract can be offered to another unfortunate soul. On the surface, Duke Elliot Baskerville searches with the rest of the Baskervilles for the seals of Glen Baskerville, to ultimately right a wrong and erase the existence of the Will of the Abyss.
