Just one day before they would've announced it themselves, Blizzard ended up leaking the first content patch for World of Warcraft: Shadowlands and The Burning Crusade Classic.
It is quite ironic that Blizzard would end up ruining own surprise after months of preparations, a day before BlizzConline no less. Moreover - these are not vague hints - press kits have all the info you'd need.
So, World of Warcraft: Shadowlands' first content patch is called Chains of Domination, and the story is as follows:
"The traitorous Sire Denathrius has been defeated . . . but the power of the Maw still grows. In Chains of Domination™, the upcoming first major content update for World of Warcraft®: Shadowlands, players will delve into new depths of the Jailer’s hopeless domain, seeking to understand the true nature of his malignant plans.
Backed by the renewed might of the four Covenants, the champions of the Horde and the Alliance will take the fight for the Shadowlands to the seat of the Jailer’s power. But the Banished One has a terrible new champion in his service—a cruel instrument of despair conscripted by Sylvanas Windrunner, capable of instilling dread into the hearts of Azeroth’s heroes like no creature of the Shadowlands."
Among the highlights are Korthia, the City of Secrets, the Covenants' retaliation against the Jailer, a new 10-boss raid Sanctum of Domination, a new mega dungeon and more.
Activision Blizzard recently said they're preparing more remasters in 2021, and we can now safely say that one of them is World of Warcraft: Burning Crusade Classic.
" Originally released in January 2007, The Burning Crusade summoned the heroes of Azeroth to the shattered and fel-scarred realm of Outland to stop an invasion of the demonic Burning Legion. In 2021, Blizzard Entertainment’s recreation of the first World of Warcraft expansion will give players from around the world a chance to return to Outland as it once was to relive an era of timeless adventure—or experience what awaits beyond the Dark Portal for the first time."
