Infinity doesn’t exactly live by this rule super hard. It kinda already went out the window with the Nomad Motherships, dreadnoughts, and the Circulars themselves.
Yep. The Minotaur Motor is the main reason behind why we see almost every ship hitch a ride aboard a Circular. They seem to be very rare pieces of tech that you can only really find on military vessels, incredibly expensive courier ships, Circulars, or Bakunin. Everyone else doesn’t have a way to go through a worm hole unless upon a Circular which you pay a fee to do, is slower than the other options, but at the end of the day it’s still vastly cheaper compared to the alternatives. Also there’s the fact it’s like a cruise liner that has services to entertain, feed, and house passengers while going about their journey. They are said to be small cities unto themselves.
So some analogies might call it a train it’s kinda like a train, ferry, cruise liner, aircraft carrier, and then someone rolled up into one.
