Mary

Do not go to the swamp at nightfall. You have no business in the old house at the edge of the swamp.

If you find yourself there, do not believe the plaintive voices of those who will knock at your door. If you open it – you won't live until morning. The swamp Mary sees you, hears you, feels you. She is stronger, smarter, more dangerous; she has many children and loyal assistants... There is a rational explanation for all these horrors, but there are always people for whom there are no prohibitions.

Such were Stef and Ares, hunters of artifacts and everything unusual. They were brought here by a strange map and an old army flask.

Before them, a squad of similar fortune hunters vanished in the swamp. Will they be lucky – even if their plans are far from predatory?
