Generators for Vampires and Ghosts, Witches and Zombies! All you need for Horror and Halloween.
[First published Oct 2018] Disclaimer: I'm an affiliate for DriveThru RPG
This is a guide to generators you can use for a Horror or Halloween themed evening, adventure, one-shot or campaign. Themes I'd associate with horror are night, spirits, the undead, fear, the unknown and our inner doubts
Horror adventures cover stories of urban fantasy with vampire, investigators of Call of Cthulu, adventurers caught in dark realms such as Ravenloft and classics such as full moons, the evil that comes at night and cheesy horror films.

The last thing worth checking out is work the Nightmare machine, haunted places and haunted faces from the real world generated by artificial intelligence.
Zombies are another popular horror creatures, so start off your zombie horde with Zombie Descriptions and then add More Zombies. You may wish to classify them by Zombie Type. If you are feeling apocalyptic try the Apocalypse Generator
This energetic vampire has narrow blue eyes that are like two sapphires. His fine, wavy, brown hair is worn in a style that reminds you of a lionfish's spines. He is tall and has a graceful build. His skin is pale. He can command his body parts, even if they are severed. He subsists on the blood of other vampires. His outfits are usually gray.
