His metal armor clanked against the floor of the cave. He didn't care how many dragons heard him. They could cower in the shadows of his new empire.
When the experiments had first started he was just trying to help the people. Find better ways to defeat the dragons. But now that he knew how, he could kill them all.
A better life for the humans.
The Shadow was his invention, his creation. The people looked to him for a new, brighter future.
So he walked the halls of his base, listening to the screams of the dragons. The poor unsuspecting dragons. They didn't even know it was him doing this. Ha. They didn't even think the "scavengers" were capable of coherent thought. This would be their downfall.
