The Crow — Legacy: Challenger's Proving IV

Crow's eyes are stern. His voice is strained with worry. He tells you he swung by Nessus; stopped by a Vex conflux near where you hit those Psions. He was worried and had to ease his mind. Glint tapped into them and managed to dig out a corrupted Cabal transmission from that site. It could be nothing, but they traced it back to Europa. Crow would feel better if a friend were to check it out.
