Selm, a Duke of Hell whose title is Prince of Possessors, is the nominal ruler of those devils with the ability to possess the bodies of mortals.


Selm stands seven feet in height, his heavily armored hide seeming to be formed of colorful leaves of dangerously alluring beauty. His eyes can petrify at will, and massive spikes protrude from his arms. A small disk embedded in his chest prevents any fiends of possession from harming him.


Selm reports directly to Asmodeus, Overlord of the Nine Hells.


Selm nominally commands the six Lords of the Possessors, six possessor devils of greatest power.

  • Thyle
  • Cykes
  • Tyd
  • Nausyyd
  • Dyclex
  • Hyrkovan


At one time there stood beneath Selm a council of six lesser nobles—Thyle, Cykes, Tyd, Nausyyd, Dyclex, and Hyrkovan—but since an ancient rebellion in Baator (in the original article, this was Baalzebul's rebellion as described in Dragon #28; however, this event is no longer considered canon, and the only other major rebellion was the Reckoning of Hell), his six inferiors have allied with one another, gradually assuming much of Selm's power. Selm's place is now a merely nominal one, though officially he is still the chief, and only he receives orders from Asmodeus. This is a potentially explosive situation, so both sides remain on their guard.

Publishing history

Possessor devils were originally detailed in Dragon #42 (1980), which is also the only source that mentions Selm. Other variations on the idea of possessor devils include the mezzikim from Guide to Hell (1999) and the Fiend of Possession prestige class in Fiend Folio (2003).
