The spell called "spiritual projection" or "astral projection" brings the caster to the Twisting Nether instead of the Shadowlands; and the Twisting Nether is also referred as "realm of ghosts". However, both planes don't appear to be related, as Outland is floating on the Twisting Nether, but the Shadowlands can be reached in Outland in The Burning Crusade.
In the opening cinematic, Sylvanas shatters the Helm of Dominion, breaching the veil between the material realm and the Shadowlands, an ancient dimension where the dead coalesces for judgment. Sylvanas' actions have upset the natural balance between life and death, and it's on players to enter the Shadowlands itself and repair the cycle before it is too late.
During the Burning Legion's third invasion, the Knights of the Ebon Blade traveled to the Shadowlands to acquire the Aggregates of Anguish, five tormented essences of powerful souls - Admiral Proudmoore, Soulbinder Nyami, Grand Empress Shek'zeer, Grand Apothecary Putress and Archmage Arugal. Salanaar required these to conjure the Steeds of the Damned for the order's new Horsemen.
But we know that the mission table feature will return in some way, thanks to a Hazzikostas interview with Twitch streamer and professional World of Warcraft tank, Sloot. In the interview, Hazzikostas confirmed that mission tables are present in Shadowlands, and that Blizzard wants it to be something you can do on your phone, rather than a front and center feature. Hazzikostas also stated that the team is looking to evolve the gameplay and offer more for players.
The Shadowlands has long been referenced in World of Warcraft lore, but their origins and true nature remain a mystery. One thing is for certain; the Shadowlands are inextricably tied to death and decay. It stands opposed to the verdant spiritual realm of the Emerald Dream, which represents a vision of reality untarnished by corruption and mortal intervention.
The final destination of the spirits of the deceased remains a mystery to the priests and philosophers of Azeroth. However, as spells such as [Resurrection] can reunite a dead body with its spirit, and a majority of living creatures from the tauren to the troll shadow hunters claim they can communicate with and call upon the power of the spirits, a widely held belief is that the spirits of the dead remain on the Material Plane — in an immaterial state that can only be altered or contacted through the use of magic.
Since World of Warcraft’s 2014 expansion, Warlords of Draenor, the MMO has used some kind of mission table for players to gain passive bonuses while logged out of the game. Two years later, Blizzard introduced a mobile app, which let players send followers on important missions while far away from their computers. But with the upcoming Shadowlands expansion, it seems Blizzard is trying something a bit different with missions: an autobattler.
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.
This section contains information that needs to be cleaned up. Reason: The death knight realm has already been confirmed to be the Shadowlands. Sylvanas committing suicide from ICC in EoN has already been connected to the Shadowlands. Reword still unclear things, move confirmed things to the main section of the page or remove them entirely if they are already incorporated there.
Spirit healers decide when it's time for a mortal soul to pass into the Shadowlands. When a mortal dies and their soul crosses the veil between life and death, it is shepherded by the kyrian to Oribos so that they can be judged by the impassive Arbiter. All of the soul's contents—deeds, misdeeds, thoughts, accomplishments, and failures—are instantly laid bare before the Arbiter, who then judges in a mere instant and sends the soul off to one of the infinite realms of the Shadowlands, each of which is ruled over by a powerful Covenant. The Covenants are ancient and powerful orders who have existed since the Shadowlands were shaped long ago, and who bear sacred duties to help maintain the afterlife's ecosystem. Not every soul is filtered into the main four Covenants. Each soul brings with it a vital force known as anima, the product of all of the soul's experiences and actions in life. Anima is the lifeblood of the Shadowlands, making trees grow and rivers flow and is the source that's drawn upon to conduct the magic of death. Great souls—both good and evil—have a lot of anima, while those who have lived humbler lives have less. Four of the realms—Ardenweald, Bastion, Maldraxxus, and Revendreth—are especially vital to the functioning of the Shadowlands. However, there could be infinite afterlives, some small and tailored to a single person while others are vast and full of either splendor or torment. Between each realm is a cloudy space which was once rich with streams of anima connecting the different domains, but the current anima drought has caused the realms to become cut off from one another, breeding fear and mistrust among the inhabitants.
