This is the successor mod to Princes of Darkness for Crusader Kings II. Same team has developed both mods.

Princes of Darkness is an overhaul of the base game, aimed at bringing the World of Darkness into life in Crusader Kings 3. As such, it has many gameplay concepts altered, and use the extensive lore of its world to propose a different experience all around.

The first thing to note is that, as a Vampire, you are immortal… sort of. You won’t die of old age or disease, but being put to the torch or decapitated will still end your unlife. As such, succession is a lesser, but still present, concern for you. In the same vein, Marriages can’t produce children, so they are mostly a political tool available to a select few religions. Religions are a core part of the gameplay, even more than in CK3. Here, it represents the core philosophical tenets of your character, which help him not fall to the Beast. Indeed, the Beast -a literal manifestation of your inner monstrosity- is one of your worst foes, and managing your stress is paramount to not fall prey to it, as it would mean your character has become a feral wight, resulting in his abdication. Take notice of your hunger, a core modifier representing your need for blood. Hunger is used for many schemes and powers, and replenish slowly or with active hunting.

Vampires are slow at learning new things. As such, you still have access to the base lifestyles, but at a lower rate of progression. You can instead choose to invest your time into the disciplines, opening the powers of the damned for your use. Buildings represent your influence over the mortal populace. Most are capped by a stat like control and you will have to choose how to balance these. Note that major centers of populations, represented by high development duchy capitals are the biggest asset any Prince can dream of. Warfare is sensibly altered, with a bigger emphasis on knights. The prowess of your knights can easily overcome a much more numerous foe, especially if mostly composed of levies. As such, be very wary of high prowess hostile Vampires. In a world full of deceit and tricks, intrigue plays a bigger role. There are new schemes to discover, some linked to your powers, and most of the characters have secrets better left untold… or used for blackmail if their religion allows it.

The World of Darkness is an universe running for more than 30 years now, with hundred of books and other medias covering it. The main idea is that, in our world, several factions of supernaturals creatures are interacting below the surface, creating an underworld full of intrigues and stories. The Vampires of the WoD are mainly the result of the biblical curse against Caine, the first murderer, and most are tracing back their lineage to him in a system they call ‘generations’. This dynasty tree of the undeath has branched into several factions, the clans, each with its strength, weakness and geographical power base. In Dark Ages : Vampires, which you are playing now, we are following the undead world at the crossroad of several major crisis. The sack of Constantinople has happened, and broken the major Cainite Empire of the time, having a ripple effect as far as France and Persia. Meanwhile, the Church Inquisition is gathering support and information, almost ready to usher the age of retribution on the cursed bloodsuckers…

1230 AD: “The War of Princes” is the period of conflict in Cainite history that began shortly after the fall of Constantinople to the Fourth Crusade in 1204. The term refers to the conflicts over territory that the various princes of Europe fought after the end of the Long Night. The War of Princes began shortly before the Inquisition was formed. Although the Inquisitors were initially used as tools by the elders, they soon became a greater threat to the Cainites than the Cainites were to one another. Although it is not clear exactly when the War of Princes ended, it would have likely been forced to a conclusion with the advent of the Anarch Revolt, if not sooner. Will you be able to win conclusively the War before the mortals start their uprising against their rightful masters?

Thank you for your interest and support

Kayodewolf, ultimogeniture should be the youngest, but also Knights of Acre should only be ordinating adults, not children. So it should be your youngest ordinated adult. We have added to our dev build the ability to also designate your heir for a prestige cost. What militant order of chaste knights would recruit children?!?

Ordination creates a fictional kinship relationship between adults in the order. Because we don't have proper theocracy mechanics in CK3 and in the game you play a dynasty. So you find a mortal adult in your court and use the ordinate decision to bring them into your primary character's dynasty as their "child". Its like the vampire embrace scheme, except its social/religious rather than magical.

There is a lot of information in the wiki about the mod. We are continuing to add to the in game tool tips and encyclopedia. It is a never ending process.

ENS, there has not been an update in CK3 nor POD since yesterday.
Try looking at the last few lines of your error log at someplace like: \Documents\Paradox Interactive\Crusader Kings III\logs\error.txt

Also, the mod should have size of 1.94 GB (2,092,204,249 bytes) or somewhere around that. If it does not, you have an incomplete copy of the mod and you should redownload.

We have heard reports that the latest CFP is incompatible and crashing. We don't plan to work on a patch for CFP until after ModCon.

Mod keeps crashing, which is weird because yesterday it was working perfectly with the same mods I am using today. Did something update?
kayodewolf Sep 28 @ 7:24am 
Great mod, lots of new stuff to do. BUT, it's so confusing because there is barely any information on anything. For example, I tried to play as knights of acre. The instructions says that you can have a child through an character interaction with a someone that is younger. However, I have done that with as many courtiers and children that I can find, and none of them show a become squire or ordinate interaction. Now I am wondering maybe it's because I am too old or maybe you can only have a certain amount of children or maybe the children must be order members first or maybe... In the end, the mod is awesome because it transports you away from the slow and eventually boredom of Ck3 into another word with NEW stuff. Nevertheless, it is a little off-putting because it's hard to find any information about what you can and can't do. Anyways, if anybody can help with the knights of inquisitors heir and knighting information, I would be really grateful. Thank you.

crusaderstar, prowess is still relevant for duels, some schemes and some events.

I don't know how a commander's prowess figures into a battle.
crusaderstar Sep 27 @ 8:41am 
Just learned that in vanilla CK3 your rulers never fight as knights in battles and so am wondering does my 80 prowess commander camilla (playing as him, and he isn't listed as a champion) contribute to the fight like a champion? And if not, could he :D :D :D ?! Maybe just as a thing where if everyone else is beat and commander is last one left, they too fight? Would be so cool!

Multipass, the last option, obviously.

Well lorewise the deal was 100 souls to corrupt, but he has failed within deadline so I suppose duration of contract has became indetermenate. Important lesson, I would assume, is not to make deals with infernal.

Has anyone managed to stop being asked for sacrifices as lukas of the drowned monastery and if so how? i already killed my father and grandfather to no avail.

Thorn-Exile, make sure you have a full download. Also, try to play POD without any other mods installed (like CFP).

If you want additional help, you should indicate at minimum, when the crash happens for you.
