Ravenloft's Domains of Dread are some of the most terrifying locales in the entire multiverse, but they're not simply pocket planes full of jump scares and disfigured monstrosities. Each Domain of Dread exists to imprison a Darklord—a villain whose crimes were so profound that they drew the attention of the Dark Powers and were bound within a pocket dimension that twists and torments their darkest desires.
In this article, we explore five infamous Darklords from the 17 included in Ravenloft: The Horrors Within, examining their pasts, the nature of their domains, and the powers that make them deadly and unique threats.
![]() Strahd von ZarovichPast. Strahd von Zarovich is the quintessential and most infamous Darklord. Once a ruthless warlord whose campaign conquered the land now known as Barovia, Strahd’s envy and desire drove him to murder his brother Sergei and attempt to claim Sergei’s beloved, Tatyana. His pact with dark forces transformed him into the first vampire and empowered him to slaughter his entire family and retinue of followers. Present. After Barovia was claimed by the Dark Powers and turned into the first Domain of Dread, Strahd has brooded within Castle Ravenloft, eternally pursuing reincarnations of Tatyana to no avail. Though he occasionally toys with adventurers, he is relentlessly cruel to those who deny him his desires. Domain of Dread. Much like Strahd, Barovia exudes classic gothic horror. Isolated settlements are dotted amongst perpetual mists, deadly monsters roam the countryside, and all who try to scrape a meager living are assaulted with a constant, repressing atmosphere of dread.

![]() CthulhuPast. Cthulhu is unlike most Darklords. Instead of a mortal twisted by ambition, it is a primordial cosmic force from beyond reality. For eons, Cthulhu has warped worlds by invading dreams, unraveling minds, and shattered the boundaries between reality and the Far Realm. Present. Now imprisoned within the Domains of Dread known as Innsmouth, Cthulhu can only wield a fraction of its terrible might. Even while bound, Cthulhu sends its dreams to seep from its prison and into realms beyond, guiding its cults and manipulating weaker minds toward rituals that might free it. Domain of Dread. Innsmouth is a domain suffused with elements of cosmic horror. It is an inhospitable expanse of alien mountains, drowned ruins, and what remains of the cult-infested community that lends the domain its name. These bleak expanses are home to twisted creatures and warring cults. Signature Abilities

![]() Viktra MordenheimPast. Dr. Viktra Mordenheim is Ravenloft’s resident mad scientist. Driven by her obsession with anatomy and reanimation—as well as a lack of conscience for the living—she was able to resurrect her deceased partner through science rather than magic. Present. In Lamordia, Viktra’s relentless experimentation continues in her castle-laboratory: Schloss Mordenheim. Aided by constructs and chemically animated Undead, Viktra toils endlessly to replicate her greatest invention, the Unbreakable Heart, which allowed her to reunite with Elise. Domain of Dread. Thanks to Viktra’s industrial influence, Lamordia is a domain of body horror and environmental destruction: Toxic byproducts run off into streams and are dumped in forests, all while abominations born from unchecked experimentation roam the icy landscape. Signature Abilities
|
![]() AnkhtepotPast. Once a high priest who betrayed his pharaoh out of ambition, Ankhtepot was cursed by the gods with undeath and stripped of his ka, the vital essence of his soul. Present. Now ruling Har’Akir as an immortal pharaoh, Ankhtepot is indifferent to power for its own sake. His sole obsession is recovering his lost ka, so that he may die and face the gods that cursed him for eternity. Domain of Dread. Har’Akir is a land of obsidian sand, ancient tombs, and relentless heat. The lone city is ruled by an authoritarian priest in Ankhtepot’s name; meanwhile, below the sands, a labyrinth of interconnected tombs rife with traps and terrors spreads for miles. Signature Abilities
|
![]() EbonbanePast. Ebonbane is a sentient weapon forged from the collective malice of evils vanquished by the hero, Kateri Shadowborn. As Shadowborn and her retinue destroyed darkness, lingering evils imbued the shards of her shattered blade which her foes reforged into a conscious, evil weapon intent on corrupting its wielder. Through manipulation and whispered promises, Ebonbane ultimately orchestrated the downfall of Shadowborn and her allies. Present. Now confined to the Shadowlands, Ebonbane is bound to Shadowborn Manor unless carried forth by a mortal wielder. Ebonbane seeks to dominate those who wield it, using them as instruments to destroy its ancient enemies and any lingering ideals of heroism. Domain of Dread. The Shadowlands is a realm of corrupted heroism and lost ideals, divided between haunted Avonleigh and zealous Nidala. Here virtue is often a mask and excuse for cruelty. Signature Abilities

Posted May 22, 2026If a magic cursed sword is on the same level as Cthulhu, then that's gotta be a real powerful binding on cthulhu

Posted May 22, 2026The change in Strahd story is a little disappointing. He was the liberator of Barovia and that what made his fall greater. I pre-ordered the book(cause I'm crazy for anything Ravenloft) but I prefer the setting in the 2nd Ed and 3rd Ed.

Posted May 22, 2026Okay, to walk back one comment of mine: It could be interpreted in the original work that Dagon is another name for Cthulhu. While I'd prefer the name Dagon used in Innsmouth, its not my call.
They could have gone with:
Dagon, the Demon Lord, has some aspect in the Domains of Dread. Could be the Demon Lord got caught, could be something with coming from another reality all together.
Dagon, a separate entity but not C'thulhu, is within the Domain of Dread.
Or.. Dagon is C'thulhu, C'thulhu is in the Domain of Dread, and in this case we don't bother with the former name which seems to be the way things went.
Still think its a bit strong of a thing to put along side a sentient chunk of metal and the upstart vampire, but that's just me.

Posted May 22, 2026Likely because in D&D Dagon is a Demon Lord (one of the obyrinths in fact) and not an Old One like Cthulhu, their domain the 89th layer of the Abyss, known as the Shadowsea actually sits right below Demogorgon's layer the Gaping Maw.

Posted May 22, 2026True, but expanding the lore a little bit and having a (lesser known, if still powerful) demon lord trapped in Ravenloft (possibly leaving his layer exposed to takeover) would actually be interesting.
And a conflict between the drak powers and an Obyrith would be way more interesting, from a D&D point of view, than just chucking in Cthulhu.
But WotC have become allergic to making plot/lore advancements. All established characters have to stay forerer where they are...

Posted May 22, 2026There are TONS of elder evils that have barely been touched in 5e.
Make a Domain of Dread for Hadar, or Atropus, or Father Llymic, or Gaernoo, or Hargut & Haask, or.........

Posted May 22, 2026Honestly it would have had the same energy if they reflavored an aboleth, but I suspect that this was mainly to hammer home the point that they can finally add Cthulhu to an official D&D Book since they are now in the public domain something that they haven't been able to do since Arkham House had licensed all mythos related properties to Chaosium for the first edition of Call of Cthulhu and threatened TSR with legal action over the first print of AD&D's Deities & Demigods. Besides they couldn't use any properties or powers that Cthulhu is reported to have in any works that are not in the public domain- thus another reason why they are likely watered down.

Posted May 23, 2026Very disappointed about Victor Mordenheim being erased in favor of current politics. Also, agreeing with an earlier commenter that Obed Marsh would have been much better choice than Chtulhu for a dark lord. But still, looking forward to getting the bundle.

Posted May 23, 2026If you go back to what Lovecraft actually wrote, Dagon probably was Cthulhu.

Posted May 23, 2026well yes but it says in the article about the new ravenloft book that the darklords pure unbounded evil but cthulhu is not evil he is neutral and also he is still too powerful. but as a creature to fight he makes sense because he is not actually a god he is just a super powerful alien the actual gods are incomprehensibly all powerful

Posted May 24, 2026Bit strange how Cthulu is a Dark Lord here. I can kinda understand it as a concept. But when you have to say that he still has the ability communicate with the outside world when they are supposedly being contaminated, is it really worth it?
