Dormizite -- These are dropped by dormant basalt rumblers. These rumblers are stealthed mobs in the Lava Field; they will not aggro (break stealth) if you are stealthed or invisible. Look for them in the box canyon around ( -602, -44, -543 ) /waypoint -602, -44, -543.
Bouldering Heart -- These are dropped by the boulderings surrounding Tyrock near the Broken Spire -- ( -606, -45, -568 ) /waypoint -606, -45, -568.
Return to Bunglegreeder who instructs you to search for information about King Tranix.
The remains of Weldin are deep within the Roekillik caves which have entrances on a few sides of the peninsula on the beach by the giants. This is in the South-West corner of the map. Follow the shoreline from the Coldwind Station Griffon Tower, the first cave entrance that you come to you will need to take these turns (immediate dead ends are not counted) once inside the caves to find the bones: LEFT, RIGHT, RIGHT, RIGHT. In the second entrance you need to go LEFT, RIGHT, RIGHT. In the third entrance (where the druzaic shrine appears) you need to go LEFT, LEFT.
This skeleton is inside the Lamia Cave at ( -335, 2, -630 ) /waypoint -335, 2, -630. You can see the cave entrance from the dock at Chomper's Pond. Once in the cave go LEFT then go RIGHT. You will see the bones on the edge of the path. It is easy to get turned around in these caves, so take care not to miss any tunnels.
Edgarin in The Feerrott -- ( -1932, -23, 557 ) /waypoint -1932, -23, 557
Go through the Bitterwind Trench passage and straight across the Jagged Plains. Once you are on the opposite wall and facing the passage, look to your left and you will see a leaning ice block. The bones are in the open space under the block.
This location is just through the first mountain pass (into the same valley that houses Asphyxia) and at the bottom of a small crevice. The skeleton is skewered on a spear that is stuck vertically into the ground. The crevice is filled with a searing lurker spiders that like to hide.
His bones are laying next to some boulders in the open area just past the underground Temple of Solusek Ro. When you exit the cave from the temple, follow the left side of the zone and it will take you to his bones.
Enter Solusek's Eye and find the chest on sublevel 5. The chest is on the left side of the room where various Giants of Thyr first appear. ( 100, -357, 189 ) /waypoint 100, -357, 189
NOTE: This is the room with the teleporter disk, so be sure to get its access by stepping onto it the first time you are here. Thereafter you can use the disk at the Drednever Expedition site to return here.

Return to the chest in the giants of Thyr area ( 100, -357, 189 ) /waypoint 100, -357, 189 for your reward. You can also return to Fendaris K'Lorn and inform him of your success for an interesting dialog.
