Northern Greenshade, between Moarmer Camp (to the west) and Moonhenge Wayshrine (to the east).
Shard at this location is found inside Barrow Trench – public dungeon. The dungeon entrance is close to a nearby river. This is a location of map that is most rewarding with their shards. Just before you enter the dungeon you can grab an additional shard “No longer entrenched”. When you enter the dungeon, grab a “The Unfilled Order” quest from a delivery contract at the start of the cave. This quest leads you toward the last part of the cave. This is where the most of the public dungeon shards are found. In this case, this is not the same situation.
As you enter the dungeon, turn left at the first crossroad. Just before the door that helps you escape the last cave room, is the collectible we are searching for.
