Certainly, shattered systems are the result of powerful precursor tech - but given the Epicenters and the lack of indications that the Trigs possess the same level of power (why would they reside in a tumultuous Abyss if they could manipulate space to the degree that the tech employed to facilitate Seyllin or Thera’s & the others’ eruptions demonstrates?), I’d say we have yet to make contact with a civilization capable of ruining systems as we’ve seen with
Tangentially, the indicators of the identity of those responsible for the eruptions surrounding Caroline’s Star and Seyllin (by means of deduction) point to the mysterious Talocan race as being somehow involved with the tech responsible for it all - the Epicenters that are present in every shattered system are the largest body of evidence in this case as of yet.
