I started a quest found on a book that I really cant remember where I have to look for the sword of Red Eagle. I did the quest and then later in the game I talked to the Jarl of Markarth and got another quest for hunting Red Eagle leader down. When I go to do that quest I find the leader dead since I killed him when I was looking for the sword of Red Eagle before. His corpse is there and the objective marker is on top of his dead body. I go back to the Jarl and the quest doesnt seem to finish... please help out whenever you can...
