1x Dying Berserker Questioned
What battle?! Those troops were on a recon mission!
And what's this talk of Alliance - you're sure he said Alliance?
Listen to me, [player]! I need to know what's going on and I need to know NOW!
Get yourself down there and get me some answers! Scour the battlefield and look for survivors - clues - anything!
