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).
At the heart of the Maw lies Torghast, Tower of the Damned, a cursed otherworldly prison where the wickedest souls in the universe are locked away. Highly replayable and inspired by roguelike games, heroes are invited to explore its ever-changing halls and chambers and do battle with the minions of the Jailer, Torghast’s vile ruler. Those who brave its trials can claim legendary treasures and help free the heroic spirits wrongfully trapped within.
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.
Certain playable races will receive new customization options (for example, humans will be able to customize their ethnicities, dwarves and trolls will gain tattoos, and undead will be able to show varying degrees of decay). The Death Knight class (added in Wrath of the Lich King) is being opened up to pandaren (added in Mists of Pandaria) and to all allied races (added in Legion and Battle for Azeroth); players who pre-ordered Shadowlands received access to death knights for these races with the release of Patch 8.3.0, Battle for Azeroth's last major content patch, on January 14, 2020.
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.
The experience curve is adjusted to make it faster than ever to prepare for the newest challenges, and each level along the way will provide more meaningful increases in progress and power. All expansion zones are getting more flexible, too; they'll be able* to scale to you and your friends while you level to 50, so it's easy to try a zone you've never played.
The Torghast experience is in a true alpha state. It is not yet feature complete and many design decisions are still being made. Due to our desire to get pointed feedback on class-specific Anima Powers, we are only testing a few classes at this time. When it becomes available to play on the alpha, the following classes will be available for testing: Demon Hunter, Mage, Priest, and Warlock. We will keep you updated on when other classes are introduced.
The origins of the Shadowlands remain uncertain, but they have existed ever since mortal life first arose in the physical universe. They span all worlds, including Azeroth, on which Icecrown serves as an anchor to the Shadowlands. There are those who believe mortal souls are drawn into this dark place when they die, remaining there forever. Others hope their souls will go on to a brighter place rather than languish for eternity within the cold confines of the Shadowlands.
