Zephyr (西風(にしかぜ)旅団(りょだん)) is one of the preeminent jaeger corps in Zemuria and their rivalry with Red Constellation is almost as well known as their prowess on the battlefield.


Zephyr was led by Rutger Claussell, known as the Jaeger King, until he and Baldur Orlando of Red Constellation resolved to settle the question of whose was the strongest jaeger corp with a personal duel. When the duel concluded with the mutual death of both participants, Zephyr seemingly disbanded.

Two of Zephyr's regimental commanders, Leonidas and Xeno, were hired by Duke Cayenne and served the Noble Alliance he commanded during Erebonian Civil War in late S.1204.

It is later revealed that the group continued to operate in secret and are pursued a mission to bring back Rutger. They succeeded in this in S.1205.
