“If you found a system only containing a darkness homeworld, it would be no different than finding nothing. If finding such a system is essentially the same as not finding a system, it seems most reasonable to treat it as entering an empty system while searching for planets. I mean... you can always assume that the alternative is that there is nothing there. ”
This is essentially what I was going to post before Scarlet did. If you want to imagine that it was an empty system, you can do so. There's a lot of systems out there, with varying degrees of value.
There are very very very very few with no value, the fact that the first system found was at the time, the only "worthless" one, is statistically amazing, and likewise hilarious.
