* IAmNotShazam: The ''product line'' is called "Ravenloft", but the ''place'' is called "the Land of Mists" by those of its inhabitants who actually call it something other than "the world". To them, "Ravenloft" is just a big old castle in Barovia.
* MoralEventHorizon: To be honest, ''all'' darklords have crossed this line; the Dark Powers would not grant a Domain to someone who hasn't. But a few darklords have done things that are unspeakably evil even when compared to the others. Notable Acts of Ultimate Darkness (defined on the main page) by the setting's Darklords are:
** Count Strahd Von Zarovich's murder of his brother Sergei over Tatyana, the woman both men loved, on their wedding day, leading to Tatyana throwing herself off the wall of Ravenloft as Strahd pursued her.
** Lord Soth committed several major acts that would qualify as Acts of Ultimate Darkness:
*** He and his first wife, Lady Korrine of Gladria, had been trying to produce a son to be his heir, and Korrine had consulted a witch about the problem, who had agreed to help them, but had warned her that the child would be a representation of Soth's soul. Unfortunately, Korrine didn't know about the bad shit that her husband had done, including ordering the murders of his half-brother and sister by his seneschal Caradoc, else she would have known what would eventually transpire of the birth and would be of a mind to curse the witch. When she gave birth to the son in question, it had a face similar to that of dragon-kin with two arms on one side and a leg on the other, with the last leg placed at the bottom of the buttocks as if it were a tail. To say that Soth was pissed about this was a massive understatement, and thinking that she had cheated on him with some kind of demon, Soth murdered both Korrine and the monstrous child.
*** After marrying a second wife named Isolde he set out on a quest to stop the Kingpriest from unleashing the Cataclysm upon Krynn by forcing the Rod of Omniscient Wisdom into his hands (according to Isolde's vision, it would take many tries, and each time he was killed, he'd rise with greater power) in return for redemption. When Soth and the thirteen knights with him found the Rod, he left his soul due to the curse on the coffer, and was now a type of {{Lich}}, with his soul residing in the coffer like a phylactery, astrally projecting into his body, and unaware of this new state. On his way to Istar, he came across three elf-maids who proceeded to poison his mind about Isolde, telling him lies about her infidelity and saying that she had sent him on this quest to die in order to get rid of him. Soth got pissed again, returned home and confronted his wife just as the Cataclysm began. A chandelier fell on Isolde and their newborn son, and she begged for him to save their son, but Soth stopped himself from doing so, so as to prevent his own son from growing up as he himself had. With her final breath, Isolde cursed him to live the lifetime of every soul that he had caused death on that day, and as Soth's keep burned down, Soth became a Death Knight, and his retainers became undead.
** Azalin Rex's execution of his own son after catching him freeing political prisoners.
** Lord Wilfred Godefroy beat his wife and daughter to death with his walking stick because his wife hadn't given him the son he wanted.
** Harkon Lukas abusing his position of the "Grandfather Wolf" in order to bring civilization to his homelands, driving out [[OurWerewolvesAreDifferent his own people]] in the process. Interestingly, the Act wasn't enough to catapult him to Darklord-dom; rather, it was using the colonists [[ImAHumanitarian as a food source]], which isn't normally a powers-check worthy act for wolfweres-rather, it was the betrayal of trust.
