Prepare for adventure!
After defeating the undead monsters in the Beng'eryn Woods (see Bastions & Beholders), you notice that one of them had a tattered and stained scrap of parchment on them. While the damage makes it difficult to read, you can make out just enough to realize that it's a map! It looks like it leads to a treasure chest, one of the many that were stolen from the gnome wizard Tupp O'Weir. If this chest is anything like the first one (see Arcanums & Aboleths), you will need to sign the scroll that lies inside the chest. Onward!
