Nights of Nightmares is a lost island in the ocean, a place no one reaches by their own free will.

Here, nightmares walk; they have semi-human forms, and humans have ceased to be hunters, becoming prey instead.

In the center of the island lies the District of Hunger, a territory ruled by The Lady, also known as The Dame, who governs alongside Mayao and is inhabited by giant creatures that represent humanity's phobias, just like everything else on the island.

Each inhabitant is different. Some are hunters, others guardians, others simply live their lives in peace, and others work for the Cathedral, where The Lady rules.

The only known entry and exit is guarded by Blop, a huge sea creature that, for the inhabitants of the island, is a friendly whale, but for humans, it represents the final obstacle to freedom.

Now you must choose your path:

Be a nightmare, a living phobia. Be part of the world that dominates the island.

Be a farm human who escaped from one of the Cathedral's farms; you must keep anyone from finding you, or be a lost human who arrived at Nights of Nightmares by accident. Use your resources and find a way to escape.

On this island, everyone has a fear.

The question is: will you be the one who causes it or the one who survives it?
