Daughter of Arcana and Atlas, before they became gods, Polyxo fought in the Demon Spawn War (89 GE - 269 GE). With skills more suited for the lab than the battlefield, she was posted north of Cthorgo with the Tholanbar military unit. This was a battalion sized force of Turkûn and auxiliaries tasked with building the bastion of Quelmollendë and watching for demon incursions.
At Quelmollendë, Polyxo dabbled in Creation. After obtaining a source of life energy, and in collaboration with Silvanus, they created the Myconid race. Polyxo's other notable creations are the carrion crawlers and the ochre jellies - both to serve as the "vultures of the underworld".
Polyxo also experimented with soul energy, at Quelmollendë, creating the first Derro.
After the Demon Spawn War, Polyxo became a Solar to her mother Arcana. Polyxo's skill at using life energy and soul energy is such that along with her magic items she is equivalent to a Sentient Creationist.
