In Destiny 2: Lightfall, Neomuna was added as a free-roam world.
Neomuna is a technologically advanced human city hidden on Neptune. The city survived the Collapse because its inhabitants entered cryogenic stasis and preserved their consciousness in the CloudArk, a vast digital infrastructure tied to the Veil. When Lightfall begins, Emperor Calus and the Witness’s Shadow Legion attack Neomuna to seize that mysterious power.
The destination introduced a neon-lit urban setting unlike earlier patrol zones. Guardians travel through districts such as Liming Park, Ahimsa Park, and Zephyr Concourse while fighting Shadow Legion forces and Vex. The city’s defenders, the Cloud Striders Rohan and Nimbus, help explain Neomuna’s history and its isolated society.
A common mix-up is confusing Neomuna with the Last City. The Last City is humanity’s principal settlement on Earth and the main social hub for Guardians, while Neomuna is a separate hidden colony on Neptune. The Dreaming City is also a distinct Awoken location, and Freehold is not a current Destiny 2 patrol destination.
