Archimedes was a crude admixture of invention and man, though he would call himself the pinnacle of what man can become. He wore green, brown, and purple robes mixed with bronze metal for all of his various innovations that made up his cyborg body. His right arm had been morphed into a long, constructed tentacle along with an entirely bronze leg. It is as if the entire right side of his body had been completely merged with metal. On his back, he wore a large series of tubes and a couple of bronze-protected tanks of dark pink liquid.
He was known to be the leader of the cult of Ke’Kauhale, and he was first encountered on the deck of the Riddle of Lightning where he and his cultist companions boarded and stole a Kraken Sealbreaker. He then teleported away, back to Ke'Kauhale, along with one of his goons. He was later encountered with a Sending spell to Oriz, where he warned him and the Destined against challenging him further, to which Commander Hieros attacked the party after Oriz's denial.
Archimedes was encountered deep in the Third Segment of Ke'Kauhale, where a final encounter against him and his cult was had. It ended with Archimedes's death at the hands of The Destined, with the help of emissaries from Iroas, Phenax, and Thassa, and fighting against emissaries from Erebos and Pharika.
