Description

Greetings, my friend.

You have proven yourself to be a worthy hunter, ready to stalk the greatest of creatures and succeed. My injury is not healing this time, and I fear that my wife is right and my time on the hunt is near the end. Yet, I still have knowledge of what needs to be done, so I am pleased to continue to guide you if you so choose. The dream wraith is a particularly difficult foe, as not only does it posses knowledge of magic and of death, it can invade your mind and turn the world into a living nightmare, freezing you with fear. It is also difficult to find, as it exists partially in the world of dreams, and thus is not always easy to see. Of course, I will reward you with ingredients from my wife's stock, but for this task they will be of the most valuable kind. Are you willing to slay these foul creatures?
