Walkthrough
-
Talk to 'calm' Archaeologist and, after a brief conversation, accept the quest. He will then offer to teleport you to the Rex Matriarch Lair. While you do not have to accept the teleport right away, there is no real reason not to.

Once you have teleported, or made your way to the lair entrance, activate the teleportation device to enter.

Once inside, head East and talk to the 'calm' Archaeologist. He will tell you about the best discovery that no one else has found... Bones! Oh my. Unfortunately, before he can work his fossilomancy on them he needs to be able to get to them, hence why he needs you since he still needs to prepare for the ritual. He will advise that there is an inactive teleporter in the beast's lair and that if you can get it working, you will be able to reach the bones. A dragonkin crystal should do the trick.

On the other side you will find a balcony with a pile of soil. Uncover it to reveal a Crystalised rubble pile. Excavate the pile until you receive a $ilnkfull32211. While excavating, you will also obtain some $ilnkfull31179, note that 20 are needed to repair the crystal.

After restoring the $ilnkfull32212 you will need to make your way back to the Rex Matriarch Lair and speak once more to the 'calm' Archaeologist, there will be a cutscene showing you entering the lair and Osseous being born. Unfortunately for the 'calm' Archaeologist, Osseous is a bit famished and will eat him while you manage to escape to safety.
