Sieghart

Sieghart was a legendary hero and the very first of the Sieg Knights of Catarina.
Born to unknown parents following the appearance of the First Flame, Sieghart made friends with Aldricius, who would later become the first King of Catarina, after they fought in the War of Souls.
Sieghart is credited with cutting the dragon Sinh, a Great Dragon, from the sky using the power of the Storm Ruler sword, crafted specifically for him by Aldricius, when he was a blacksmith.
Following the slaying of Sinh, Gwyn promised Aldricius a land of his own to rule as a kingdom in the place where he found the magic metals that were used to craft the Storm Ruler sword, with this promise being fulfilled after the War of Souls is finished.
