Gelugon

Insectile ice devils are strategists and masterminds in Hell's armies, using their superior intellect to strike against their enemies and spread Hell's influence throughout the planes. An ice devil rarely breaks their solitary contemplation of strategy save to pursue a plan they have devised. They can be enticed otherwise only by an exchange of services to be determined at a later time, adding to the pieces they can play on the board. Occasionally, a mortal strategist of outstanding skill might amuse an ice devil enough for the gelugon to agree to a contest of strategy, typically a strategic board game like chess, to decide a dispute. In the unlikely event the devil loses such a contest, they inevitably go to great lengths to later obtain that mortal's services for their own infernal ends.

Masters of corruption and architects of conquest, devils seek both to tempt mortal life to join in their pursuit of all things profane and to spread tyranny throughout all worlds. The temptations they offer mortals range from great powers granted by the signing of an infernal contract to twisted favors following a whispered pledge to a diabolic patron, or any number of even subtler exchanges. Those who succumb to these temptations find themselves consigned to an afterlife of endless torment in the pits of Hell, wherein the only hope of escape lies in the chance of being promoted to become a devil in the infernal ranks. Every devil has a specific role to play in the upkeep of the remorseless bureaucratic machine that is Hell, from soldiers and scholars to inquisitors, lawyers, judges, and executioners. Lowly lemures and imps perform subservient labor to more powerful and specialized devils, such as contract devils and erinyes, while the greatest pit fiends command entire infernal armies.
