For lack of any better term, R3X-TRµΓ1A∩ was discovered when a party of Pathfinder Society agents were dispatched to investigate what appeared to be a lost tomb whose entrance had been uncovered in the Mindspin Mountains. Much to the surprise of the dwarven explorers, the tomb appeared to be for some kind of human hero rather than dwarf, so the Pathfinders were notified.
After a harrowing adventure through the tomb's traps and denizens (some of unexplainable technological origin very similar to things and creatures attributed to Numeria, the final chamber was found to be...completely destroyed by what could only be described as a colossal collision from untold centuries in the past. A strange metal container had collided with the mountain and penetrated all the way to the tomb, the tunneling path to which had been carved upwards towards the peak.
While greatly dismayed the historic value of the tomb had been ruined as the cost of excavating this remote site in its dangerous environ was beyond the reach of the closest Pathfinder Society lodge, the agents were to be surprised when their presence suddenly activated some type of mechanism which hummed with power and glowed with magic(?) to suddenly eject a humanoid being along with bizarre liquids which quickly began to evaporate or be absorbed by the rocky ground.
While clearly not human, the creature shared the same shape and limbs, but upon opening its eyes, they suddenly lit with illumination while precise and geometric lines punctuated here and there with circles appeared on it skin. And so R3X-TRµΓ1A∩ was born. Of his past or reason for existing, he had no knowledge. The only thing he appeared to know was how to speak and write his designation: R3X-TRµΓ1A∩.
Initially wary, the Pathfinder Society lodge soon discovered R3X-TRµΓ1A∩ willingly absorbed any knowledge they provided. They dubbed the artificial person Rex Trulian given how it looked when Rex wrote it out in whatever language it originated. He showed an unusual interest in magic, but seemed incapable of producing it himself in the usual manner. Instead he began producing strange recipes or formulae which appeared to replicate spells which could target oneself, but no one else ever seemed to get the same results from the formulae when they used them. This did not seem to deter his unfailing desire to produce formulaic code for all spells he encountered.
After another Pathfinder member visiting the lodge where Rex had been learning displayed what he called a firearm, Rex replicated it using small cast-off pieces of his own form. Using this device, Rex was finally able to produce effects similar to offensive magic using the same alchemical origins.
After some years with them, Rex's almost uncanny skill in understanding language and the engineering fields, the Pathfinder Society sent him to Magnimar to learn the languages of old Thassilonia and Azlant in order to to assist with expeditions in this region.
What fate awaits our curious android? Only the gods may know.
