A five-minute video sums up what changes in Azeroth
Blizzard has published a video of almost five minutes that explains what World of Warcraft: Forever is. It covers the new zones, the Skyborne, the classes and the raids. Forever sits next to Classic and modern WoW and replaces neither.
The video appeared on 23 September on the official World of Warcraft channel. It speaks to three groups at once: Classic players, players of modern WoW, and people who have never played Warcraft.
The numbers
Forever brings more than 1,000 new quests, a new playable race, four new zones, nine new dungeons and two new raids, says Blizzard in the video. Those figures match what was shown at BlizzCon and are on the Forever page.
The focus is on levelling. The road to level 60 is meant to be the heart of the game, with account-wide rewards that make every next character count. That is the Legacy system.
Where the idea comes from
The spark was Season of Discovery, says Blizzard. Familiar zones were full of secrets there, and players worked together to find and document them. Forever takes that feeling of discovery and makes it bigger. Members of the Classic team worked on the concepts for years.
What the new zones show
A fork in the road in Redridge Mountains that always ended in a dead end now leads to The Riverglades. Alliance players meet the Brotherhood of the Horse there, not seen since Warcraft II. Horde players meet an ogre clan, and the Twilight’s Hammer is the threat.
Mount Hyjal is the finale of levelling and holds both new raids. On the mountain sits a camp of Horde and Alliance together. They got trapped in the same place and now keep an uneasy peace to survive.
The Skyborne and the classes
Among their own people the Skyborne are called the Shen’dorei. Their home, abilities and look are built around the sky, the elements and the spirits that sustain their civilisation. The racial 
Walk on Air turns a fall into a controlled glide. They can join the Horde or the Alliance.
The new race and class combinations include the Dwarf Shaman, the Gnome Priest, the Human Hunter, the Orc Mage, the Troll Warlock and the Undead Paladin. Every class gets changes, so that every specialisation is viable in combat without losing what makes it unique, according to Blizzard.
Dungeons and raids
Group content starts early: the first dungeons sit around level 15. Most raids are built for 10 or 20 players. Onyxia’s Lair stays at 40, and more raids of that size will follow now and then, between the updates for 10 and 20 players.
Barrow Deeps, the raid for 10 players, has eight bosses and lies beneath Mount Hyjal, says the video. The video calls Onyxia’s Lair available at launch. The roadmap puts the raids on 9 December 2026, five weeks after the launch on 4 November.
