Activate the Well of Echoes.
Travel deeper into the Infinite Forest.
- The Vestibule is an entry point into the Forest itself.
- Make your way carefully across the platforms in the darkness.
- This leads into a cylindrical room with a staircase looping to the left.
- Follow this staircase upwards.
- This will lead to a Vex Activation ring.
- Step into the ring at the top of the stairs.
- Wait for it to activate, then shoot the Intelligence Cube that is in front of you.
- This will bring in one of the numerous Reflection of Osiris.
- It will bring in a platform into existence, allowing you to continue forward.
- Head along the path forward, listening to the various Reflections talk, passing along what they know.
- Following the path will lead you directly to Infinite Forest.
- At the entrance into the Forest itself, one of the Reflections of Osiris will have plenty to say to the Guardian.
