Access the H.E.L.M. via the Director and select "A Hollow Coronation." Then connect the recovered Atlas Skews to an Atlas Terminal.
With the Atlas Skews collected, a star chart begins to take form in your Wayfinder's Compass. Each Skew provides a portion of a sequence that can be used by the Caliburn Gatehouse to create a bridge to a hidden location. There are still missing pieces you will need.
"I have updated the gate in your H.E.L.M. with coordinates to a chamber deep within Reef space. Bring the Skews. Each one is a portion of a sequence you will need." —Queen Mara Sov
