I guess it's a small consolation for those fireteams who wiped in VoG, and woke up in orbit with a sore ass and no memory of the past few hours. Vex always seem the creepiest when they kill you... standing over your body and using their x Ray beams to do who knows what. In seriousness, curious about why they uploaded the captain's consciousness in that Nessus sidequest. Was it a reward, a punishment, or merely ambivalent curiosity?

There a misconception here. Their erasure doesn’t affect things outside of the Vault of Glass. Every Guardian who was “erased” inside the Vault are still “known” outside of the Vault. The reason Kabyrs fireteam forgot them is because they were in the Vault when the erasure happened, so it affected their memories. Everyone outside of the Vault would remember who the others were. The issue becomes: when the people who knew them die, no one is left to know they were ever around in the first place. Phanin was killed by Dredgen Yor. That is a long time ago. Since then there have been several major battles and a good numbers of Guardians have died.

There were probably more, but since vex erasure means that everyone that went in was forgotten, the vanguard must've sent in wave after wave sending them to their doom. Pahanin probably broke that cycle. If you stand in any major vex areas, you can see ghosts popping in and out of time, most likely from those doomed firetreams.
