Corborus – Deathwing enslaved the massive gyreworm Corborus and drove it to unearth the vast amounts of elementium required to forge the Dragon Aspect's new plating. With Deathwing's departure, however, Corborus has broken loose and now rampages through the Stonecore in blind fury.
Slabhide – With his powers as the Aspect of Earth amplified by the Old Gods, Deathwing easily swayed Deepholm's stone wyrms into serving the Twilight's Hammer. One of the most ambitious of these creatures, Slabhide hopes to earn Deathwing's favor by exterminating any intruders brazen enough to enter the Stonecore.
Ozruk – Ozruk has served as Stonecore's guardian since Deepholm's creation. It is unknown why Ozruk has remained in the Stonecore, but it has become apparent that the guardian now believes that anyone opposed to Deathwing is a threat to Deepholm, and should therefore be destroyed.
High Priestess Azil – High Priestess Azil is one of the few who has survived communing with the Twilight's Hammer cult's eldritch masters, although little remains of her sanity. She instills terror in lesser cultists so that they will sacrifice themselves without hesitation when their masters command it.
