Publisher's blurb:
A Starfinder Society Scenario designed for 9th- through 12th-level characters.
Ever since the Starfinder Society first established a presence on the false moon of Salvation’s End, its agents have continued to slowly but surely uncover new information about the megacomplex’s internal machinations and the dangerous Guiding Intelligence seemingly at its head. But they’re not the only ones interested in Salvation’s End…
Deep within the false moon, the tyrannical Vault Lord conquers vault after vault, spreading their influence and subjugating the residents of every vault in their path. Now, the free residents of Salvation’s End have come to two conclusions: the Vault Lord must be stopped, and they’ll need to work together to defeat them.
Join the Starfinder Society, the free citizens of Salvation’s End, and the mysterious Guiding Intelligence in a joint attack against the Vault Lord within the very heart of their realm: the vault of Xin-Tsalash!
