Complete strike "Tree of Probabilities" and defeat Cabal on Mercury to collect Traces of Osiris.
"Osiris moved through the Forest as a god. We must deal with the repercussions as mortals." - Brother Vance
- Having completed the first quest step, it is time to move onto another, starting into the Strike, "Tree of Probabilities."
- To collect the Traces of Osiris, you simply need to find and kill any Cabal that are about on the planet (but not during the Public Event).
- Depending on your fireteam, you could have to run the strike twice or simply run around Mercury after having completed the strike.
- When this second quest step is done, it is time to head to the directory for Mercury.
