Well another thing's for sure, only 3 knossoses were encountered. The gamma drac knossos, nubula knossos, and the knossos that lied beyond the nebula knossos in the binary star system.
Here's is as follows, when you see a knossos, on the other end of the jump node there won't be one. That's why we only encountered 3 and not 6.
Apparently it only takes one knossos device on one end of a subspace node to keep that node stable, because when you get into the nebula from gamma draconis, you don't see a knossos on the other side of that subspace node. And when you encounter the second knossos, when you go on the other side of that, there isn't a knossos on the other end of that node. And in the binary system where you'll end up at the end of the second knossos subspace node, 150 clicks out you'll see a 3rd knossos where all of the sathani are coming from. And chances are, yet again, on the other end of the subspace node of the third knossos there won't be another knossos. It's quite apparent it takes only 1 knossos device from one side of a subspace node to keep a subspace node stabilized.
