Find 3 Hidden Wyrmtongue Caches on the Broken Shore.
Not all demons on this shore stomp around in the open. Some slink about in the shadows, finding more subtle ways to advance the Legion's cause. I have been observing the behavior of smaller demons, these wyrmtongues. They seem to spend considerable time acquiring objects of power. We cannot allow them to use these items against us. The wyrmtongues stash their goods in chests spread around the Broken Shore. I suggest you relieve them of their ill-gotten gain.
