What Lies Beneath is an Event found within The Deep. Enemies gather around an abandoned drill that can be unlocked and opened once the enemies have been cleared from around it.
What Lies Beneath starts when encountering a party of Balgrim bandits gathered around a drill. Defeating this mob will grant access to the drill containing Archaic Bone.
There is not much loot other than the Archaic Bone in this quick event.
