"And those hatchlings in the incubation chamber... they're just the tip of the iceberg. Over the years, Black Steel has been attempting to mate with various monsters to create an offspring capable of fully inheriting the energy of the earth's veins."
Dragons, lesser dragons, humans, and any other high-level creatures on record.
The majority are through mating; however, Black Steel forcibly injects his genes into the bodies of those that refuse to cooperate.
This thick stack of research reports is Black Steel's "criminal record" from over the years. He closely monitors the birth of those offspring. Initially, he was unable to properly control the earth's vein energy, resulting in malformed offspring that perished shortly after birth. Nowadays, he can stabilize the state of the young more effectively.
But even that doesn't satisfy him.
In Black Steel's eyes, these young beings are far from his ideal state and hold no value in existence.
