I had assumed, when the beacons were found in Lave, Eravate and around Jupiter that this was what he was referring to. I think those led to the discovery of one of the alien wreckage sites. Of course it could be completely unrelated.
Ahhh, that might be the case - although the beacons around Lave and Eravate mean you don't need a Sol permit. Also, throwing non-Rift clues into the Rift thread makes things here even more complicated than normal.
So, possible, but not definitive
