World of Warcraft's next expansion Shadowlands is in development.
Featuring 4 different Covenants that you align yourself with to level up and gain unique powers, transmogs, mounts, and, unique quests. (Think class halls, but not just for your class).
Shadowlands will feature a hub city a lot like Dalaran named Oribos, The Undying City. This city will feature a new currency that is obtained in Shadowlands, replacing gold.
The end dungeon is named Torghast. It is ever changing and inifinite, giving new difficulty through changing switching rules of engagement when fighting monsters. It can also be faced alone.
Shadowlands is releasing this fall .
