Furthermore instead of being a Blueprint of Azeroth it’s a Blueprint of all Worlds including both the Realms of Life(due to touching upon them as the Lore Book of the Emerald Dream Zone) and the Shadowlands(as shown by Ardenweald being called a Mirror of the Emerald Dream).
The Blueprint has every World on an endless plain. There are no planets in the Emerald Dream.
The Spirit-empowered Blueprint isn’t the only endless plain in existence as the Veil(formerly called the Shadowlands before the Realms of Death were discovered) is also an endless plain containing a mirror of all Worlds themselves and is a nightmarish labyrinth of Decay.
