Kill Sunhawk elves until you find the Sunhawk Missive, then return it to Vindicator Boros at Blood Watch.
It is good to see you again, [player]. I have a quandary that you might be able to solve.
Our agents situated behind Sunhawk lines have reported seeing Sunhawk soldiers parsing an unusual document.
Unfortunately, we have been unsuccessful in acquiring a copy of the document for ourselves. I need you to go out in the field and try to recover the document. I am certain that if you apply enough pressure, a Sunhawk agent will turn over the information we seek. I leave the use of force to your discretion.
