Every nightmare leaves a mark. Marked Horror Blockheads is a collection of horror-inspired entities trapped between legend, folklore, urban myths, and forgotten nightmares. Each Blockhead represents a unique manifestation of fear — stalkers, predators, cult leaders, parasites, revenants, queens, hunters, and things that should never have existed. Every entity is documented through an official Character Card, recording its classification, threat level, behavior, relics, lore, and current status within the archive. Some are contained. Some are hunting. Some are growing stronger. And some have already escaped. From cursed highways and abandoned hospitals to haunted cathedrals and forgotten carnivals, each Horror Blockhead carries its own story, abilities, and place within the growing nightmare. No two entities are the same. No two encounters end alike.
