To the people of the Core Worlds, Reavers are a campfire tale and bedtime story; to the people of the Border Worlds and Colonies, Reavers are very real.

Reavers are believed by most of the 'verse to be men that went insane at the edge of space and became savage. They stared into the void beyond and became what they saw: nothing. They gave into their primal nature and all that was civilized was discarded.

Showing no care for life, they are driven by an insane, homicidal and xenophobic aggression that manifests in the cannibalism and torture that they visit upon any unfortunate enough to come across them.
