The factions in the Blood King’s begin with the Blood King himself, bored and disdainful, but under the right circumstances willing to see the Player Characters as more then a food source. Around him is his court and its guests, several of them quite alien, but all wanting something, and in many cases having something to hide. His daughter—who of course, is the one sending dreams to the Player Characters of an imprisoned princess—plots with a desperate vassal and other allies to supplant her father. His mother—or is she?—now a Banshee, lurks, seeking recognition by her son. Below the mansion, the Blood King’s pet, the Blood Spider Queen, grown big and fat on diet of blood, wants her court to be the equal of his. Elsewhere, the vampire hunter, thought lost a century ago, hides out behind a barricade of traps, waiting for an opportunity to strike at the Blood King... All of these factions want something and see the Player Characters as a means to strengthen their hands. Some will prove to be the allies the Player Characters need to survive The Halls of the Blood King, others not.
What this all means is that The Halls of the Blood King is not an adventure at which to go full tilt. Players and their characters wanting to rampage their way through the halls and room of the Blood King’s mansion, will first face guards with flesh-ripping blades and then the vampires themselves. The immunity from mundane weapons, the charming gaze, and the ability to drain Levels combined their numbers means that the vampires are too tough to face directly—and that is for Fifth Level Player Characters, let alone Third Level. Instead, the Player Characters need to find a less direct way to deal with the Blood King and his vampires. The scenario provides several, including gathering information, finding certain important items, and of course, creating alliances. Whilst there are opportunities for combat in the scenario, what this means is that The Halls of the Blood King is much more of a social and roleplaying scenario than it looks at first sight. Whomever the Player Characters decide to ally with, they have a chance to really change the status quo at the Blood King’s court.
More social minefield than gory bloodbath—though it has plenty of potential to end that way—The Halls of the Blood King is a genuinely challenging adventure, presenting a highly detailed and atmospheric vampire lair in which the Player Characters will have to tread very lightly if they are to survive, let alone succeed.
