Call in the Artillery (Horde)

Objectives
Use the Artillery Flare to target the Northern, Northeastern, Southwestern, and Southern buildings at the Twilight Gate. Provided item: Artillery Flare
 * Northern building targeted
 * Northeastern building targeted
 * Southwestern building targeted
 * Southern building targeted

Description
A pity that we're no longer allowed to drop the Plague on our enemies. It would prove quite effective in this situation. Oh well, at least we have war machines to destroy their precious gates.

I want you to take this flare. Use it to mark each of the four buildings within the Twilight Gate to the northwest. The war machines will handle the rest.

Rewards
You will also receive: (or  at max level)

Progress
We need those buildings to be marked if our bombardment is to be effective.

Completion
I must say that I rather enjoyed the sight of their buildings being hit.
