Lore Lesson: The Archfiends
There are 7 Greater Archfiends and 13 Lesser Archfiends. Each of the Greater Archfiends own their own demiplane that resides on the edge of the Abyss. The fiends should not be worried about! They do not seek the destruction of the mortal realm, as they only seek to subjugate its people under their specific sin. The archfiends usually interfere with each other’s plans, though alliances are not unheard of. When the Archfiends were banished from the Mortal Plane, the Greater ones created their own demiplanes on the rim of the Abyss; there are only 6 planes, however, as it is believed that Sathanus, the Archfiend of Wrath, had fallen into the Abyss when they were first banished.
