A barghest is an awakened canine. They look like mastiffs, usually pure black or white, and among their characteristics are glowing eyes and a spine clearly visible beneath the short fur. Their howl can put their prey, and humans definitely count, into a catatonic state, at the very least it induces fear.
Trained barghests are highly valued as guard dogs. It is rumoured that the maximum security prison on Silcox Island is guarded by free roaming barghests, among other nasty things.
