ジークベルト・ザイドリッツ

Siegbert Seidritz was an Imperial flag officer and had served as the captain of Kaiser Reinhard von Lohengramm's supreme flagship, the Brünhild. He served in this position from at least 799 UC and had participated in all engagements involving the Brünhild from the Battle of Marr-Adetta onwards until, presumably, the passing of Kaiser Reinhard.
