Darkpass

A city left alone from the people, the place that is feared. Once you go there, you may never come back. People oddly disappearing when they are close to it or even in it, nobody comes out, ever. Legends also encircle that city, it is said that demons and angels walk around freely, the rarest that werewolves and vampires also live in that city full of darkness and fear.

Nobody's dares to go there except for nineteen year old Azula. She isn't scared of the city instead she feels as if it calls to her and begs her to come closer to it. So she does.
