By and large, your failures in Torghast are measured in deaths, not with a timer. Dying repeatedly alerts the Tarragrue, a lumbering iron-clad creature that will appear at the level’s entrance and slowly move toward its end. If he sees any heroes, he will chase down and kill them. If he reaches the end of the level or kills all the players in the level, your run ends and you are thrown out of Torghast.
Claim a covenant's power: players will be called upon to forge a bond with one of four covenants that rule Shadowlands' new zones, setting the tone for their journey through the expansion with a full covenant campaign. As they level up, they'll get new abilities based on their choice, including class-specific abilities for each Covenant—as well as developing soulbinds with specific covenant members, which grant them access to that character's specific traits and bonuses.
World of Warcraft's next big expansion is Shadowlands, set in the realms of the afterlife. The Horde and the Alliance will set aside their faction war to chase a new evil, known only as The Jailor, who has usurped the natural order of life and death. The game is currently in closed Alpha testing, and seems truly awesome thus far (a preview on that is coming soon).
Shadowy Tormentors inhabit this dimension, and emerge from it to torment death knights such as Koltira Deathweaver. The Lich King originally kept them at bay, but after the Knights of the Ebon Blade left his service, the tormentors are now loose upon them. He even appears in the World of the Dead, as he calls it, riding a frost wyrm during  The Power to Destroy.
The Shadowlands are accessible upon death, where the player-character can roam, and can only be seen by other spirits. The Spirit of Tony Two-Tusk describes the Shadowlands as all grey and dark, swirling clouds. While Uuna was in the Shadowlands, she described it as dark and she was unable to see anything, though she could hear people interacting with her in the physical world. From within the Shadowlands, she could see the light of the naaru A'dal who was in the physical world, but it was so bright that it scared her. The moonlight at Lake Falathim allowed her to see a friend in the physical world.
