Get Back Here! (Horde)

Ginsa is also the regular flight master - look for the flight icon underneath the temple of the jade serpent on your map.

Threw me off a little as I was expecting to see a separate NPC with a kite in the temple just for me!

Your bag will contain a Horde Missive ("A hastily written and violently sealed letter"):

"Enough frolicking about, Itzakiri!

Have you forgotten our directive?

Final preparations must be made for our offensive, and I need you here.

Put an end to whatever distractions you're engaged in and return to Grookin' Hill at once.

-General Nazgrim"

... which amuses the hell out of me as I imagine big orc men like Nazgrim frolicking in the park.

Currently there's something wrong while we're about to turn in the quest:
The quest preview window (the thing attached to the questlog that shows quest-relevant NPCs) will show General Nazgrim, wearing Sergeant Gorrok's armor.
