Lost Colonies
You've taken time to honor the lost colonists of Titan, and the next logical step is to visit the Exodus Black. The Exodus Black was meant to establish the first extrasolar colony before it crashed on Nessus. Failsafe may be able to help you find ways to honor the colonists who were lost in that disaster.
Speak to Failsafe on Nessus.
"I saw the Fallen destroy the people of Zephyr Station. It was awful, but at least I died there with them. I cannot imagine how the people of the Exodus Black felt to encounter the Vex, alone and unaided." —Saint-14
