Canoloth

Canoloths are yugoloths fiends who are frequently employed as contracted guardians. They diligently fulfill their part, not exceeding it one iota.

Description
Canoloths are fiendish trackers and guardians employed by individuals of evil intensions. They prefer to enter into contracts to guard valuable treasures and important locations, always doing exactly as asked — never any more, never any less. Unless instructed to kill, a canoloth merely holds on to its prisoner.

Appearance

History
In the Genesis ward of Aeor, the Mighty Nein encountered one aeorian nullifier who was joined by a creature described as a canoloth. Until it could even realize itself, the canoloth was banished by Caduceus, and then hastily avoided by the group.
