Those logs basically tell you things to not waste your time on search, yet you somehow manage to misunderstand.Read it carefully bud. I've made bold and Italic on the important bits.
"Melville thinks the Synuefe XR-H D11-102 system represents some kind of end point or ‘last colony’. Beyond that, the sites appear in ciusters, with the number of sites in each cluster getting increasingly larger. We discovered a cluster of sites* only a few days ago before finding a location with an entirely unique layout. So far we’ve found three sites in each of the following systems: Synuefe LY-I b42-2*, Synuefe NL-N c23-4* and Synuefe TP-F b44-0*.
There are basically three different types of site, (Dreamstate edit; which are already all present in those 3 systems mentioned - so why mention unique layout when this paragraph clarifies?) present most of which have a different codex layout. Melville thinks that each type of site fulfilled a different function. He also thinks the Guardians were the dominant species in this region of space. But he’s not content with this discovery. He wants to keep going.
Are we ever going back to turn back?"
Edit: the * denote the mentioned systems.
As a side note, those logs were before the Guardian Sites have been found and there had been only one type of ruin site known to date, as it only talks about the Guardian Ruins. We know of a lot more than 3 or 4 different layouts, as we now have Guardian Sites too.
