Yeah.
Mages can loot that in Scarlet Halls and then buy the portal spell in Dalaran (requires level 90).
It basically teleports you to where dalaran used to be, which is pretty up high compared to the crater left in there.
I’m pretty sure there was a portal from Dalaran to the same spot during Legion. It’s still given to Paladins at the beginning of their class hall campaign (they can bubble).
