This is it? You found it?
In the case of the Scriveners I single Fdev would have made a single jump following the conclusion of the Orion University CG and then left it 'to rot' as you put it. Even with a radius of 500 LY it's a huge area to search and we previously failed to locate it after the previous jump from the Hesperus only a little over 200 LY away. As such it's a needle in a haystack, yet I see no reason Fdev would have outright removed it.The Scientia Aeterna, only known asset of the Orion University, is still in HIP 43670, forgotten and left to BGS rot. It's a dockable megaship.
The positions of the Scrivener Dredger and the Golconda remain unknown. With jump ranges like 500ly per week (and potentially even more with Golcondas new hyperdrives), it is practically impossible to locate them through brute force. The spheres one would have to comb through, by now, contain hundreds of thousands, if not millions of systems.
Personally, I believe that both the Dredger and the Golconda aren't even in the game, until an article or some other hint state so. The statistical probability of finding them by sheer luck do not justify the developers effort to care for them and move them around. Same with the Phagos clan and the Artificers.
The only remaining dredger clan that could still be in the game, is the Blue Viper Club, because GalNet hinted at it, when they escaped Archon Delaine's revenge after conspiring to overthrow him.
Billions. After ~30 weeks they could be halfway to the Core by now. Agree that the simplest answer is that they are deleted from the game until needed again. But it's fun to imagine that they're still out there, and it's not like it costs the developers anything to leave them in and park them in some anonymous system 10,000 LY out.The spheres one would have to comb through, by now, contain hundreds of thousands, if not millions of systems.
Is there any creditability that the Dredger clans communicate with each other? Such that finding one may lead to the others?
Some are true loners while others have formed alliances, or occasionally gather to increase their gene pools.
