Warlock of The Fiend | Monster Guide for 5e

Warlocks of the Fiend gain their powers through magical pacts forged with archfiends of the Lower Planes.

These warlocks often keep imps or quasits as companions, and they tend toward philosophical extremes: consorting with fiendish cults or dedicating their lives to destroying such cults.
