Dominox, the Grand Demon of Loathing, is a powerful demon bound to an engine in Aeor. As an NPC, he is played by Matthew Mercer.

Description[edit | edit source]

Dominox is a demon that preys on insecurity.[4] He can communicate and influence the behavior of others through whispers and showing them visions of things they fear or regret.[5]

His symbol consists of two overlapping circles of unequal sizes, crossed with several lines.[6] Dominox can take on multiple forms; that of a small girl with long, dark red hair,[7] or that of a massive demonic entity.[8] When injured, its blood becomes chains when it falls to the floor.[9]

Biography[edit | edit source]

Before Campaign 3[edit | edit source]

During the Age of Arcanum, Dominox was bound to an engine in Aeor via an Abyssal soul anchor to serve as a power source.[10] His powers were neutralized via seals.[11]

According to Teven Klask, while many devils hoped to defeat Dominox, he had not been seen since before the end of the Calamity.[12]

Campaign 3: Bells Hells[edit | edit source]

Evoroa told Bells Hells that Ludinus Da'leth was in Aeor, but his efforts to uncover Aeorian tech had lately found resistence from something called Dominox.[13] Bells Hells, following this lead on behalf of the Exandrian Accord, encountered a Ruby Vanguard campsite in which one member had seemingly gleefully killed four others.[14] Chetney's Grim Psychometry revealed that this person had also carved a sigil into their chest.[15]

The party continued into Aeor, and found another Vanguard encampment, this one with a blood trail leading further into the level.[16] They followed it, and found it eventually reached an open chamber, the floor covered with blood, chains, and bodies, and more bodies hanging from hooks suspended by black chains from the ceiling.[17] Laudna determined the chains had been conjured into place.[18] Imogen, using a bracelet that permitted casting of Speak with Dead, learned that the Vanguard members here had also turned on each other, and that the source seemed to be the engine room.[19] Fearne called in her favor from Teven Klask after Chetney determined the energy seemed to be fiendish,[20] and Teven was able to identify Dominox's symbol as the "carving of gifting," as well as provide some history.[21] Chetney was then briefly overtaken by visions of children telling him he had slaughtered them while in werewolf form.[22] Imogen cast Speak with Dead again, this time on an ancient Aeorian corpse, and learned that the Aeorians had bound and sealed Dominox to run their engines.[10] Dorian was then overtaken by visions of his recently deceased brother Cyrus.[23] The vision of Cyrus told Dorian to resurrect him, and also showed him a vision of a purple crystal.[24] Imogen too had a vision; in hers, Liliana told her to destroy the Pinion of Service.[25] As the party discussed what to do after finding Braius, whose allies had been killed when Dominox's visions overtook them,[26] Ashton also had a vision, that of FCG, and was also asked to destroy the crystal.[27]

The party continued to a room containing the Nox Engine, where they saw a small girl with dark red hair who encouraged them to destroy the crystal and set them free. Laudna realized this was Dominox, Fearne realized Dominox was lying, and Imogen realized that they could instead take the crystal by damaging portions of the engine.[7] When the party did not destroy the crystal, Dominox shifted into its full form as it speared Chetney with a chain, and a fight broke out.[28] Bells Hells quickly were able to take the crystal and hide it in the Bag of Holding, though Dominox was still tethered to it.[29] After Ludinus entered the fight, he cast Gate into the Abyss and told the party to kill the demon there so it would die permanently.[30] Teven got the killing blow.[31]
