After generations of thinning magical bloodlines and subsequent losses in their standing in court, the Northern nobility of Calios formed an alliance and seceded from the kingdom to form the Ellerich Alliance.
The northern nobility of Calios had experienced significant thinning of their magical bloodlines for generations, resulting in a loss of their standings in court.
Coupled with political interference from the distant southern capital, the nobility decided to form an alliance and seceded from the kingdom.
Troops under the command of Houses Mesner, Caravet, and Wirna converged and fortified positions along the Wulpine Mountains
To defend their ports and prevent any sea-based attacks by Caliios, Houses Ordel and Rosar bolstered their defenses along their coastal regions.
The majority of battle took place in and around the Wulpine mountain range.
The Secession was timed specifically so that winter weather would set in soon into it. This was advantageous as the northern troops were more accustomed to the cold weather while their southern counterparts would be less equipped.
By the time winter had passed, the rebel nobles and their troops would have months to dig in and cement their positions.
Given the defensive positions along the Wulpine mountains and lack of sailing vessels for naval action, the conflict turned into a large-scale siege. One that the northerners were well-equipped to weather with enough troops to hold their positions and farmland to kept civilians and troops alike fed.
Troth was established as its own nation and the former Calian nobility regained much of its political power.
Calios lost its northern region and the majority of its mining operations in the Wulpine mountains.
The northern nobility had used the heavily anti-magic Church of Sone
to win over support of the Secession with the public, leading to Troth becoming an unfavorable society towards mages.
Diplomatic and even personal ties between the two countries and noble houses therein were irrevocably changed from that point forward.
Notably, works written in Calios following the Secession have a tendency to depict northerners as treacherous, cunning schemers.
Likewise, it's not uncommon for a Trothian writer to characterize Calian nobility as corrupt, using their magic as justification for whatever argument they make.
Due to its new aversion to magic, Trothian society soon looking more towards technological advancement that did not rely on mages. Present day, it is now the world's leader in the fields of mechanics and alchemy.
