Thulian

According to Marcus they look like anthropomorphic animals. Olga states that they are related to humans and have been allies for thousands of years but still face discrimination and bias. In Zima, the part of the Thulian Confederacy Olga is from, where they treat being a ruler as just another job.

Beastmen consider themselves humans, or at least not a completely different race (and they are technically right). They also share a lot of history, culture and other things with the humans, so it kinda makes sense that the humans would be their favourite allies. Zima (And the Federation of Thule in general) is in a near constant state of war against the Djinni Dominate, and while the Beastmen are fantastic warriors (they can even learn Aura Arts, though the process is harder compared to humans), they are completely inept as sorcerers. And sorcery is kind of the best counter against Djinni.

Thulian subspecies
There are five total Thulian subspecies, of which these are: Lycan, Felids, Minotaurs, Ursids and Verros (boar/pig men).

Lycans

 * Canine Thulians
 * Alya Vilka

Felids

 * Feline Thulians. A race well suited for night jobs. Their senses, and especially their night vision, were much better than those of a normal human, their fur protected them from the night chills and lying in ambush came almost naturally to them. Typical Felids are lithe, agile and hyperactive (Chapter 47).
 * Denam Whis - An atypical Thulian who is fat, clumsy and lazy.

Minotaurs

 * Cow like Thulians. They are exceedingly well endowed according to Merva of the Order of the Rose.
 * Sergei

Ursids

 * Bear like Thulians
 *  Olga 

Verros

 * Boar like Thulians
