Lunar Fall is the 7th major story arc in SoulWorker. It is a relativity short arc since it only consists of one raid and is the first arc that involves the SoulWorker unit. This arc raises the specter of a ceasefire agreement between Nihil's Throne and the Starry Forest League HQ if the SoulWorker Unit is able to assist with the capture of Luna Nox. The conclusion of this arc was delayed due to the Firestream Battalion's invasion and the start of the West War arc.
In this arc, the SoulWorker unit splits up into smaller teams to handle multiple tasks.
- Luna Nox
- Dipluce Horizon
- Grace City
