Southern Greenshade, southeast of Greenheart Wayshrine.

Found inside Carac Dena solo dungeon. This is an Ogre cave. They usually stand alone. Groups of two or more are rare. Collectible is, as in many other dungeons, inside the last cave room. Specifically, it is in the northwestern corner of the last room. This is a rather large room. If you are not looking for the shard you can easily skip it. The last room is guarded by Urumaz the Terrifying. This mob grants “Completed: Carac Dena” achievement upon death.

Southwestern Greenshade, east of nearby Woodhearth settlement and its wayshrine. In northeastern corner of Shademist Moors POI.

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“.

Western Greenshade, just south of Seaside Sanctuary and its wayshrine. North of Serpent’s Grotto Wayshrine.

Shard is found inside The Underroot solo dungeon. Entrance to this dungeon is approachable from north, but there are also two ways to reach it from south. Tunnel entrance close to Serpent’s Grotto Wayshrine or tunnel entrance north of Woodheaerth settlement (follow shore) lead both to a Binding Pool. This is the westernmost part of Greenshade. After you reach this point of the map continue north. Another stone entrance leads to the main road that connects this part of the zone with large island to the north. This is the area containing Seaside Sanctuary POI and The Underroot solo dungeon.

You’ll find the shard inside this cave on top of a large rock. This rock is located between the first and the second dungeon floor. As you enter The Underroot keep clearing your way toward the southern part of the dungeon. You are going to end up in a long tunnel. This tunnel leads to the second dungeon floor. Now start clearing your way toward the northern part of cave. As you reach its end you can spot the shine of the collectible in the distance. Exact spot on the second floor from where you should jump onto the rock with the collectible on it is at the entrance of the last cave room. This is the part of the cave where you can find Domina Ssaranth mob that, once killed, marks this dungeon as completed.

Guide:

Eastern Greenshade, just north of Marbruk, southeast of Falinesti Wayshrine.

Harridan’s Lair solo dungeon contains the shard. You can reach its entrance from north. This is an easy solo dungeon. Level 30-ish tigers in groups of maximum two are your only obstacle. Collectible is inside southeastern part of the cave. Bright glow from cave’s ceiling enhances the glow of the skyshard. In the next cave room, you can find Razorclaw, which is the mob you need to kill for dungeon’s completion.

Guide:

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.

Guide:

Western central Greenshade, northeast of Serpent’s Grotto Wayshrine.

Shard is found inside Rulanyil’s Fall public dungeon. You can reach the entrance if you follow the main road from south. This is a public dungeon with bigger groups of enemies and bringing a friend is a good idea. It also yields higher number of loot and exp. There are couples of strong mobs in the dungeon as well. It is probably the best to enter this dungeon at level 25+.

When you enter the dungeon, turn left and proceed toward the first room. Inside eastern part of this part of the cave, you are going to find the collectible.

There are two quests you can accept inside the dungeon. One of them is called “The Dead King“. It is given by Endarwe at the start of the dungeon. This quest has an awesome reward once completed. It gives the “Nanwen’s Crown” trophy. This trophy, when used, summons the ghost of Nanwen. The second quest is called “The Merethic Collection“. You can obtain it once you find NPC Dulini and talk to him. He sits in a corner of a passage that connects the room with the skyshard with the room to the south. Completing both quests you gain “Completed: Rulanyil’s Fall” achievement.
