Lost Messenger's Corpse - 54.2S, 82.9W
Barsinni tells you, "Come closer, friend, you might be able to help me. One of our messengers vanished on the way back from a meeting with some, ah, new associates. He was last seen in a wooded Direlands valley, around 83 W, 54 S. He was bringing back some very important information for us. We must assume he was intercepted. Find him, but most importantly, find the information he was bringing back to us!"
You search the fallen messenger's corpse and turn up a scrap of paper with some scribbled writing on it.
Lost Messenger's Corpse gives you Messenger's Journal.
