From publisher blurb: Cavians are a rat-like race of humanoids joined in a mysterious hive mind. Though they are misunderstood by many and feared at least as often, that doesn’t stop them from being an exceptional resource when someone wishes to learn of events on a global scale. Unfortunately, the people of Teryth are so afraid of a group of cavians approaching the town that a mob threatens to run them off (or worse!) unless the party can intervene. If the party can’t get to the cavians, how else will they discover what the vespans are up to? This adventure is a sidetrek in the Chronicle of the Gatekeepers Journey, and includes: An introduction to cavians, agents of the mysterious hive mind A new racial implant: the cavian mind eye
