This shard is found inside Naril Nagaia public dungeon. Entrance and approach to this dungeon is on the southern side, close to water. Dungeon is populated with level 28 humanoid enemies. They usually come in groups of 2 or 3. This is one rather large public dungeon that is good for earning experience and gaining loot. The collectible is not in the last room as you might expect, so you might miss it on your way through the dungeon. It is located in the southwestern part of the dungeon. It is well tucked between a stone pillar with a metal top and a nearby wall, in the corner of the room.
Enemy that you want to kill for achievement and completion of Naril Nagaia is found in the last cave room. His name is Archmage Camaano. He stands on a large circular platform, next to Mercano’s Journal. This journal starts the quest “The Misuses of Knowledge“.
