V. As a Stranger Give It Welcome

Overview

V. As a Stranger Give It Welcome is the fifth chapter of Polyphony, introduced in Episode: Echoes. An Echo enters the Vex Network, reaching minds within it that can respond to its call.

Original acquisition

Advance A Rising Chorus and listen to the unlocked radio transmissions in the H.E.L.M. to obtain the book entries. Use the radio interaction separately from Failsafe's vendor menu. The original episodic narrative and vendor route retired on 15 July 2025.

Reward

The unlock adds this chapter to Polyphony. This lore entry does not award a separate weapon or armor piece. The chapter can also be read in the lore archive.

Reading the retired book

Polyphony is available in the Lore menu. Seasonal book entries unlock automatically after their yearly content cycle ends, so the retired quest or radio route is not required to read this chapter today.
