Yup, that's sure a thing you can do thanks to the Princes Of Darkness mod that lets you scheme, plot, and rule as a vampire from the Vampire: The Masquerade setting. Blood is a powerful tool in the political maneuverings of medieval strategy game Crusader Kings 3, but it's an even more vital resource when your ruler is an actual vampire.
