Primus

Primus , also known as The One and Prime and the Supreme Modron, was a Greater Power and the immortal ruler of Mechanus and the modrons. While it retained godlike power within its realm, Primus was not immortal and could be killed. It is said, that Primus even existed when Aol walked on Etharis as Primus manifested itself at an unknown time. Its existence was seen as a law, a necessity for Order. And while Primus ruled over Mechanus, he never was considered a god as he was not born from Aol's spark, mortal but eternally reborn as an uncategorizable being.
Primus appeared as a large being—sometimes in a form of an androgynous gold-skinned humanoid with a face of emotionless expression. While in Mechanus, its body remained half-submerged in an energy pool within the center of the Great Modron Cathedral. Primus' form was connected to the expansive interface network known as the Infinity Web. Primus' hands always remained unseen. Its right hand was obscured by vibrant, rainbow hued radiance, and the left was shrouded in black clouds.
The Supreme Modron retained much of its form after it was slain and reborn as a vestige. As Primus was no longer bound to the Infinity Web and its energy pool, its humanoid form manifested atop a floating platform of a bronze seal, intricately linked to cogs, gears, and other revolving machinery.

Mental characteristics

Morality & Philosophy

Primus was a manifestation of perfect logic and strict order. It was linked with the plane of Mechanus and they shared the same goals and actions. While some believed it only concerned itself with the plane's modrons, others believed Primus sought to extend perfect law and order throughout the entirety of the multiverse.
It absolutely detested the tanar'ri, and held similar, if not as intense, enmity for the baatezu of the Netherworld.
