Daughter of Arcana and Atlas, before they became gods, Polyxo participated in the Demon Spawn War. Despite her skills being more suited for the laboratory than the battlefield, she was stationed north of Cthorgo with the Tholanbar military unit. This battalion-sized force of Turkûn and auxiliaries was responsible for constructing the bastion of Quelmollendë and monitoring for Demon incursions.
At Quelmollendë, Polyxo explored the realms of Creation. After acquiring a source of life energy, and in collaboration with Silvanus, they brought forth the Myconid race. Polyxo's other remarkable creations include the carrion crawlers and the ochre jellies, both intended to serve as the "vultures of the underworld".
Polyxo likewise explored soul energy at Quelmollendë, producing the inaugural Derro.
After the Demon Spawn War, Polyxo ascended to the rank of Solar, following in her mother Arcana's footsteps. Polyxo's exceptional mastery of life and soul energies, combined with her formidable magical artifacts, has elevated her to the level of a Sentient Creationist.
