A classic mix of Lovecraftian horrors, cultish zealotry, and ancient technology-filled ruins. The text is a little hard to parse in some places because of the background, but the layout is straightforward. I also wish stat blocks were collected in one place since some may be encountered across multiple locations. I like how the encounters list generally begins hinting towards a resolution since the rooms themselves are brutal enough for an adventuring party.
