The arsenal Crowley speaks of is in the cellar of a building just west of here.
It is unnerving that artillery was smuggled inside the city by my enemies, yet it might end up saving Gilnean lives today.
Find Josiah Avery and requisition the rebel artillery. We will put the weapons to good use.
Completion
Don't look at me! Leave me alone!
Notes
You need to go around the building to find the cellar door (it glows, so easier to identify). If you run around the south you won't be facing mobs on your way there.
Completing the quest will put the players into phase 4. At that instant, Avery transforms into a worgen, attacks and knocks away the player, then is shot and killed by Lorna Crowley, who continues the quest chain. Players are now debuffed with "Worgen Bite: You were bitten by a worgen. The wound looks minor... maybe it'll go away with time?"
On complete:
You've been bitten by a worgen. It's probably nothing, but it sure stings a little.
