I have been off destiny for 2 years and decided to dust off the game as of yesterday. I wanted to start where I left off and that would be with Forsaken (which I purchased yesterday). I went to the dreaming city and saw the icon for it and started it. The mission ended with me supposedly needing to meet Petra and after that, I can see nothing more for Forsaken mission wise. How do I access it? It doesn't show in the archives and now Im a little confused.
