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.

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?

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

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...
