Hello there, I'm just adding my contribution
Drew said we have to focus to the "core" of the problem. I think this is the key, with the "line" between Reorte and Riedquat. While hanging in the Formidine Rift, I was just like "wew I am looking at something I don't konw in a goddamn big area"... This can't be. I mean, something bypassed us, I'm pretty sure. My idea was to "focus at the "core" of the problem". I traced a line from reorte to Riedquat until the formidine rift, and I see there's six main star zones: DRYAEA, DRYU, GRAEH, EOWYG, DRYEAE, and finally DRYO.
First, "GRAEH" backward is "HEARG", close of "HEART" ("core" of the problem, remember...).
Second, "CORE" is only 4 letters. It can be "C0-RE" or "CO-R3" or anything in the second part of the system's name. I've already found a dozen of systems called "GRAEH CO-R ***** " ... Coïncidence?
This can be a clue, is we focus on the stars with this kind of names, we will be able to reduce a lot the field of research, don't you think ?
What's your opinion guys ? Did I smoke too much ?
Sorry for my awesome English, I'm French.
