Prologue (1) The dying man and his plans

Somewhere unbeknownst to many, a figure, whose size, width, or shape no one can ascertain, is pondering over something. He knows he is going to die in 1 billion years. No, he isn't sure why he knows he is dying or how he is dying. To most, even a millennium is long enough for everyone alive to be forgotten, but to him, 1 billion years would pass in the blink of an eye, considering he has lived for a googolplex of years.

After a while, he decides to have a successor, but he isn't sure how to choose one. For the first million years, he ponders it while reading many books. Eventually, he comes up with an idea. He would create a thing known as a system. Written in these mortal books on how it works, he spends 10 million years creating, designing, and mass-producing it. He decides to send out these systems to find potential candidates to become his successor. How many systems were made? Not even the being knew.
