From the preview, "The story takes place between The Hobbit and Lord of the Rings timelines, with an appearance by Gollum confirmed. Our main character here is Talion, a ranger moving through the wilds of Mordor. He and his family get killed by Sauron’s forces, but something tethers him to the world of the living. That turns out to be a wraith. The pair are bonded together, keeping Talion from joining his family in the afterlife. He’ll have Ranger and Wraith skill trees to level up, switching between abilities on the fly."
