Guide:
Northeastern central Greenshade, just northeast of a nearby Falinesti Wayshrine.
Shard is located on a shore of a nearby river. Riverbed in this area is surrounded by large cliffs. These large cliffs are connected via rope bridges, thus the journal hint. If you find yourself in a position where you want to drop down to collect the shard, be careful. You don’t want to die because of a silly jump.
