Well it's one concept that can relate to at least two things in the game, but feel its way more. Book report, even though it's not the entire book. In [b][i]Escape![/i][/b] - I, Robot (Isaac Asimov), an AI is tasked with building a ftl ship, honestly it turns more into non-linear space to the max. This AI is called the Brain, and it's personality, is childlike (forget the reason, thinking it was imagination). A competing company went to their AI and it basically broke down. Anyways, they asked the brain to design the ship, the brain started asking about other things, there's this whole conversation going on, and the scientist asks if the Brain could design it; the Brain replies that it had completed the design basically at the beginning of the conversation. The design is a sphere I believe 🤔, may have to go back and reread it. It's pretty funny, the two guys that have gone through all these different situations in the short stories, are about to be put through the ringer. After the ship is built, they walk up, realize it is literally (fairly certain) just a sphere, no thrusters, nothing. They enter it, there at the center, no controls...just a dial. Try to shorten this a tad. They turn the dial, basically experience death, come to, on the screen outer space, think it's 100k ly from earth. They actually left in an instant, they were there and then gone, how do we know...everyone where the ship was at, without note of launch or anything, was freaking out. Eventually the brain leads them back home through jumps, those two poor -blam!- experience death over and over. There at the end, only one scientist truly understood what had happened, how they jumped. They were essentially placed, but they had to be killed, forget the reason...but it was pretty good, have to reread. So, what am I getting at, well...it's like the traveler ping ponging between planets. (Honestly feel nessus "skipping" was a dry run, and why failsafe (kinda like the other AI here) couldn't predict it) And the ability to move world's, but I think the nine come into play on that, not incredibly important, they are actually a tool here. Edit: this isn't his only use of a sphere, there is the bell in [b][i]End of Eternity[/i][/b], which is like fate and destiny on crack. Anyone looked at the newer (I think) cover for his book nightfall and other short stories, looks familiar.

Don't get me wrong, nightfall has only a slight connection to the last city, not really connection, concept...a city overcome with darkness, buying into the hysteria of prophecy, basically killing themselves.
