I'm guessing he'd be Order. The invasion of his homeland was a year after the Great Cataclysm; imprisoning him and other members of his species in the Brotherhood after they forced the Order off the Island and broke the Lykos Resistance.

It's particularly odd that the Brotherhood defeated the Lykos, seeing how the Lykos's Culture is surrounded by the subject of war. Therefore, Polemistis being a Domo is experienced with the highest combat system: The Way of the Lykos; making him an expert in trapping, defense, and offense.

Anyways, if its five to seven years after the Great Cataclysm, he should be part of the Order, and time before that he'd be Brotherhood.
