History of I. Impact

Overview

"I. Impact" is the first chapter of the Polyphony lore book. Failsafe, the AI of the Exodus Black, wakes in a wrecked, low-power state on Nessus. Fallen Vandals are stripping her hull and most of her systems are offline. She sends a broadcast meant to draw attention to the scavengers, then approves a shader archive request from Ada-1. Later an object strikes the surface of Nessus, and Failsafe decides it may be worth reporting.

How to unlock

Entries of Polyphony unlock by listening to radio messages during Episode: Echoes. Destinypedia places the book in that episode. Ishtar Collective dates the entry to The Final Shape (June 2024), so the reported dates differ.
