The female trainer (forgot her name)located inside the shipwreck on the beach starts the quest you need. Talk to her. She gives you a quest about a missing dude that left the camp. Go straight up from the shipwreck (hope I remember this correctly, anyway someplace near) and you'll find the dude up on a column assaulted by some undead. He asks for your help and you have to kill the assailants. As a reward he gives you a dusty tome that he found and that tome is what you need.
