Main city for both factions is 'Mor´Eder' a kind of futuristic science city. Orgrimmar and Stormwind no longer exist. Kalimdor and Easter Kingdoms will drastically change and will be renamed as 'Primal Azeroth' being a unique continent. World revamp is a thing (some zones will remain, others will change a bit and some of them like cities will be totally changed). Players will discover there was an Ancient Azeroth before our current Azeroth, but that world was a failure to the First Ones who restarted the creation of Azeroth. Players will see primal races of Azeroth and this will be a new threat to both factions which will have to unite. The world has been returned to primal Azeroth, with zones put all together. The story is something the game hasn´t explore yet, something like a new story arc. Zovaal have modified time and space in Azeroth trying to destroy the world soul. At the return of Alliance and Horde leaders, time has stopped in all zones of Azeroth. 10.0 will start in 'Orgrimmar' (which isn´t Orgrimmar anymore) where it will take place the trial of Sylvannas.
