D&D Icons of the Realms: Archdevils - Hutijin, Moloch, Titivilus

Hutijin
Across the Hells, Hutijin's name fills lesser devils with fear and loathing, for this duke commands two companies of pit fiends, which make up Cania's aristocracy. With such soldiers under his command, Hutijin can easily crush any rival who gets in his way, while also providing Mephistopheles with security against armies that might seek to contest his dominion.

Moloch
Exiled from the Nine Hells, Moloch would do anything to reclaim his position. Long ago, Moloch earned his place among the other archdevils through the glory he won driving demons out of the Nine Hells. Asmodeus rewarded him by elevating Moloch to the rulership of Malbolge

Titivilus
Although he is inferior in physical strength and power when compared to other archdevils, Titivilus compensates with cunning. A shrewd and calculating politician, he has clawed his way up through the ranks to become the second-most powerful fiend in Dis, entirely by saying just the right thing at the right time to get what he wanted. Charming and pleasant, he is a master at negotiation, able to twist words in such a way as to leave his victims confused and believing they have found a friend in Titivilus. Through these skills, Titivilus has manipulated everyone along his path to power, either to win them over to his cause or to remove them as a threat.
