The Abyss Also Gazes

From publisher blurb:

When a colonist on a neighboring world disappears, a relative hires the PCs to investigate his sudden silence. Upon their arrival at the colony, they encounter an atmosphere of fear, and a plague of random outbreaks of violence. The heroes’ investigation eventually leads them to a startling discovery, one that may jeopardize the entire galaxy if they can’t find a way to stop it.
