No matter how advanced or powerful, not a single known civilisation in the galaxy has ever managed to completely cast off the shackles of fear. There always remain the mundane anxieties over politics and taxes, the rational dread of war and predation. And then there are terrors drawn from dark myths and lore: tales of haunted starfields and abandoned colonies; race-memories of mysterious ruins and forgotten races; whispers of entities hoped long extinct.

But there will always be those who scoff, who investigate…who discover far too late that there are horrors not to be dismissed, doors to remain sealed, beings who must never be mentioned aloud lest doing so summon them back to our thriving utopias and bright spaceports.

And of all such legendary beings, the darkest and most terrifying are…
Humans from Earth!

Theme: SF/Horror, stories in which humans are a source of genuine horror/terror to extraterrestrials (aliens).

Stories must involve aliens and humans/aspects of human existence, and aim to be genuinely unsettling to the (human) reader despite revolving around aliens fearing humans; thus alien characters must be relatable to readers, even if depicted as unsympathetic and/or inhuman.
