A new cave discovered on the Dragonflight PTR may give us hints of the upcoming Orc Heritage Armor questline coming in Patch 10.0.7! MrGM first shared images of the newly formed cavern, containing only level 70 wolves, though further hints and datamined information gathered from the public test realm have led to a great deal of speculation.
The cave itself is fairly innocuous, though clearly a new addition in Patch 10.0.7.
