The Arakkoa Threat

The arakkoa are smart creatures... smart as any gnome you ever met. They have this way with magic and a violent temper, however. $B$BLately they've taken to attacking Honor Hold patrols, which is why we were sent here. See, Mirren and I are world-famous marksmen, we are! But fowl and game are what we specialize in... not these... lightning-invoking birdmen.$B$BSo what do you say you give us a hand in this one assignment? You'll find the Den of Haal'esh to the southwest.
