After rumors about this possibility for the last several expansions, Blizzard has finally followed through on a level crunch. Whereas characters in the current Battle for Azeroth expansion cap out at level 120, the cap in Shadowlands will be 60—just as it was when the game first launched and just as it is in World of Warcraft Classic. Level-120 characters will be scaled down to level 50 when Shadowlands launches.
Adventurers entering the Shadowlands will find the realm of the dead in disarray. In the natural order of things, souls are sorted and sent on to an afterlife realm appropriate to the lives they lived,[5] but starting around the time of the Burning Legion's third invasion of Azeroth,[20] all souls who have perished—including the innocents slain at Teldrassil—are being funneled directly into the Maw. The Shadowlands are starving for anima even as the Maw continues to grow from the glut of fresh souls. Sylvanas Windrunner has been seemingly perpetrating acts to bring about great amounts of death and destruction. In partnership with the Jailer, they have been working toward a common end for some time.[5]

Sometimes, the spirits roam the Shadowlands without resting. It can be because their resting place wasn't complete, because of a battle in their resting place[14] or because of the corruption of their resting place.[8] To bring eternal peace to the souls, it is needed to destroy the source of corruption[15] or by making a ceremony with items such as  [Tuskarr Ritual Object].[16] A spirit in the Shadowlands can, with enough power over other souls, tear a hole into the living world once they are strong enough. This is how Jin'do returned to Azeroth.[17]
