As the title says I found a new location (for me) in Classic wow,
I wonder where is this could lead, my guess is the possible hyall raid.

It is the locked entrance to the planned but later scrapped Hyjal-raid.
This portal never got any use just like the raid entrance in Stormwind.
The entrance to the Hyjal-raid will be in the caverns of time (as it is a time travel adventure) and in cataclysm Hyjal will become a proper questing-zone.
