Catalog of Guardian Structures and Ruins

[The Reverend]

Just for my better understanding: no new ruins have been added in-game with the Trailblazers update, have they? You just added a few to the list that were there before, right?

I think this is the case, yes. People have been using the Colonization filter to locate preciously undiscovered content. Even Canonn discord revealed a lot of stuff yesterday.
I'm not sure that was an intended feature that Frontier allowed, or an oversight, but it is what it is.

Added ruins in Graea Hypue CC-H b28-27

I have been there and the layout of the obelisks is slightly different at each of the three sites: have you uploaded images to canonn or elsewhere? I took a few screenshots and can post here. It has been so long since I have done any Guardians digging that I don't remember well what is normal anymore.
Roseum Brain Trees are present in this system and I have found more in the same sector and region, though not yet in the same sector but different region.
I also recovered an Ancient Relic, to use at a suitable location closer to the Bubble (if anything odd happens will report later but not expecting it).
EDIT (5th June): The relic was rejected at the site I took it to and was destroyed as I tried to recover it but I might have picked one that needed the ancient key rather than the relic - it also rejected other relics from the same site. I have no intention of repeating the experiment.
