Unfinished Business

Unfinished Business is an Exotic quest in Lightfall that rewards the Exotic Machine Gun Deterministic Chaos.

Overview

The quest is given by Nimbus after the Lightfall campaign, and it follows the late Cloud Strider Rohan's research into a Vex-made copy of the Veil. Across its steps, Guardians gather data around Neomuna, travel to other locations, and complete the mission What Remains in the Black Garden, where Deterministic Chaos is found. The quest ends with the Guardian and Nimbus honoring Rohan and the other fallen Cloud Striders.
