A new icon datamined from the 10.1 PTR hints at a potential return to the Emerald Dream as a full outdoor zone in Dragonflight.
The theory revolves entirely around the naming convention of new icons from the 10.1 PTR. In Zaralek Cavern, players can obtain black dragon-themed armor and weapons from the outdoor zone content. These items have a very specific naming convention of “blackdragonoutdoor” in the names of the icons.
