Mechanical Overlord.
They were the very beings that still managed the mechanical factories from the old era, still fighting the never ending war.
Beings of pure reason and calculation, hard to kill and even harder to find in the current world.
For they were beings of pure energy, their very existence tied to the cosmic database. Looking to upload themselves into a physical form so that they can fight once again.
They were creatures neither living nor dead, beings that only followed the last remnant thought in their mind before they got lost themselves to the Cosmic database and became a proxy of it.
But Wilkis was not so foolish, he might have abandoned most of his humanity, but he always treated the cosmic database with fear and reverence.
It was the accumulation of universal knowledge and only complete fools will ever try to become one with it in an attempt to extract more power from them.
No, Wilkis was much smarter.
