Nimbus takes the Vex compass and Seed of Silver Wings off your hands. They don't mention Osiris insisting they stay behind, though their dampened enthusiasm says it all.

As they recheck Rohan's notes, they explain the passkey's design. The compass, tuned to the shifting unpredictability of the Nexus, should bring you right to the Black Garden's door.

There, the Seed of Silver Wings, refractive with the Garden's fluctuating DNA, should allow you to enter as if you belong.

Nimbus presses their Cloud Strider core. A whirl of nanites fly out, welding the components together.

As they work, Nimbus points out a name in Rohan's notes: the Conceptual Mind.

This is the architect Rohan saw building the Black Heart 10 years ago. It's also your best chance at unlocking the Veil, following the Witness, and bringing a worthy end to Rohan's unfinished business.

They hand over the finished passkey and wish you good luck.

Head to In.Gress to launch the "What Remains" mission.
