The Devi is a faction within Arathrum which can be considered good. They provide magical support and summoning for good-aligned sorcerers, something which did not exist (at least to a significant level) until after the Second Demonic Invasion.
History
Near the conclusion of the Second Demonic Invasion, Severus (AKA The Man) led an army into Arathrum through the Hellish Gate. Due to his immortality and ability to suppress demonic power near him, he was very successful in his counter-invasion. However, the Archdaemons were far too powerful and crushed his forces. He was blinded by Belial and cast into the chaotic wilderness. While there, he wandered the continent, murdering every demon he encountered. One day he happened upon the Juggernaut Orcus, one of the several Juggernauts deemed too dangerous to be allowed to dwell in demon society. Orcus tried to kill Severus but was defeated repeatedly. As both were immortal, they fought pointlessly for a whole year. Finally, the suppressing power of Severus whittled away enough of the power and rage of Orcus that he was no longer an evil war monster. He used his powers to grant Severus creepy flame eyes and gave him his sword. Empowered with the Daemon weapon, Severs and Orcus became the first Devi. They began converting many of the other demons on the Chaotic Plane. Eventually, they had amassed a massive army of Devi and assaulted the Archdemon lands. Much of their attacks focused on the Plane of Affliction as a quest for vengeance for Severus (Now going by Austairus, but still called The Man by the demonic armies). The juggernaut Sonnellion saw this as an opportunity to both get vengeance on the Archdaemons who had destroyed the power he once had and to fight and kill his rival Valak. Sonnellion, along with his mount Solas, each joined the Devi. Solas was greatly changed by this, but Sonnellions motives kept him from fully becoming "good." During the war, Austairus Dueled and killed (at least temporarily) Moloch. He chose to wield Drahnim (Moloch's sword) and returned Orcus's sword. Orcus returned to nearly full power and the three rulers of the Devi (Orcus, Austairus, Solas) began preparing for an attack on the capital where the Daemons of Affliction reside. [[[At some point, Sonnellion betrays the Devi and Solas gets permanently injured, he feels bad and runs and hides]]] Sonnellion summons Solas and secretly attacks the Corruption Daemon's prisons to free Loralie because he is in love with her because of some telepathy communication stuff. He also frees the Doom hoofs of their bonds and recruits them temporarily to his cause with Loralie guaranteeing that they will be allowed freedom on Aboden. Sonnellion, Solas, Loralie, and Baphomet meet up with the Devi and assault the capital. During the fight, Austairus kills Alastair, the heart of Azazel, by absorbing all of his power into Drahnim, transforming the sword into Rieschone (Fallen king in Arat).The Doom Hoof which was slain were immediately risen by the demons, rebound and even less mortal. The invaders eventually breached the throne room of the Archdaemon Belial. Both of his sons had been severely wounded in battle and had fled, abandoning him. The battle between Orcus, Sonnellion, and Austairus V Belial was amazing and then Belial was killed. Austairus, having avenged Devin, his wife, lost began to fade away. He bestowed both Rieschone and Irabis (his demon-horn sword) to Orcus and then slowly faded away back to human.
In the resolution, both sides were severely weakened. The Devi had to retreat but the demons could not follow. Baphomet led his people back to Aboden and brought Severus back with him, leaving him in a random town. The Devi set up their kingdom on the Chaotic plane. Lillith appointed her brother Rangda in secret to pretend to be Belial and convince Mortals and Demons alike that the demons had driven the Devi back. Orcus changed his name to Austria to honor Severus and remove him bad guy image, but most still call him Orcus. [[[Since Zoticus' story is that he jumps around from realm to realm, he could totally be in this story]]]
