World Of Warcraft: The War Within is the first installment of the new Worldsoul Saga, an ambitious creative endeavor for the Warcraft universe.

In World Of Warcraft: The War Within, players will travel to the new continent of Khaz Algar as an ancient civilization rises to power deep beneath the surface of the planet.

Deep beneath the surface, an ancient nerubian civilization is rising to power, aided by Xal'atath, the Harbinger of the Void first introduced in the Legion expansion. Players will need to enlist the aid of the Earthen, a new allied race available to both Horde and Alliance players, as they make their way deeper and discover an entirely new world that has existed for centuries and whose denizens are preparing for conflicts that loom on the horizon.

World Of Warcraft's The Worldsoul Saga includes two expansions following The War Within—World Of Warcraft: Midnight and World Of Warcraft: The Last Titan.

On November 23, WoW celebrates 20 Years of exploring (and saving) Azeroth. 

The first major content update for The War Within, Undermine(d) (11.1), launches early next year and will take players to the subterranean goblin capital of Undermine as players continue to chase the mysterious Xal’atath to thwart her plans.

With Undermine(d), Season 2 for The War Within will include:

• 2 New Delves, with the current ones receiving thematic updates 
• 1 New Dungeon, which will also be available in the Season 2 Mythic+ pool, along with the remaining four launch dungeons and 3 legacy dungeons.
• A new ground mount specially engineered for high-speed traversal within the Goblin city.
• And of course, a new 8-boss raid where players will face off against Gallywix and his allies throughout the city of Undermine.  

Player housing is coming in the forthcoming Midnight expansion!

The WoW team shared a teaser to conclude their portion of the Direct with more details about this system coming next year.

Key Features:

• DESCEND INTO THE DEPTHS OF AZEROTH ITSELF–Journey to a new level cap of 80 as you explore the vast empires beneath the surface of Azeroth and discover ancient civilizations, both friendly and adversarial, in four new zones: the surface-level Isle of Dorn, the industrial Ringing Deeps, the unexpectedly bright and lush Hallowfall, and Azj-kahet, a pinnacle of nerubian society.
• FORGE NEW BONDS WITH THE DENIZENS OF THE DEEP – As players progress through the main campaign, they’ll meet the Earthen that have made the Isle of Dorn and the zones beneath it their home. The Earthen will be a new allied race available to both Alliance and Horde players.  
• NEW ENDGAME PILLAR FOR WORLD CONTENT PLAYERS – Opportunities abound for adventurers looking to explore the secrets below the surface in search of great treasure. Delves are scalable world instances for 1-5 players which provide meaningful gear progression that will contribute to a new reward track in the Great Vault for world content players.
• LIVE OUT YOUR CLASS FANTASY– New Hero Talents for each class specialization will provide players a way to progress their characters with evergreen self-contained talent trees that also infuse class fantasy flavor inspired by iconic Warcraft universe archetypes such as a Mountain Thane for Warriors or a Dark Ranger for Hunters.
• EXPAND THE POTENTIAL OF YOUR ALTS – With Warbands, players can enjoy account-wide progression with all characters in their Battle.net® account, regardless of faction, that includes shared War Within renown, a warband bank, achievements, and more! Additionally, a new change to transmog collection will let players learn the appearance of any gear type, even if they cannot equip it!

World Of Warcraft: The War Within is now available with the World Of Warcraft: Midnight expansion currently in development.
