The Arseid school (アルゼイド流, aruseido-ryuu) is a swordmanship style developed, practised and taught in Legram, Erebonia. The school has its origins in the knights of the Eisenritter, led by St. Lianne Sandlot during the Middle Ages. They played a crucial role in supporting Emperor Dreichels, which led to the school gaining great renown over time. Even today, people visit Legram from all over the country to seek training under Victor S. Arseid.
It's one of the two most famous martial styles in the Empire, the other being the Vander school.
