Stronghold Legends - Siegfried

Siegfried in stronghold legends loves using the ice tower. He will say "what a gross giant" when he makes giants. He is a better enemy than Dietrich and will attack with a stronger army. 
Sigurd (Old Norse: Sigurðr) is a legendary hero of Norse mythology, as well as the central character in the Völsunga saga. The earliest extant representations for his legend come in pictorial form from seven runestones in Sweden and most notably the Ramsund carving (c. 1000) and the Gök Runestone (11th century). As Siegfried, he is one of the heroes in the German Nibelungenlied, and Richard Wagner's operas Siegfried and Götterdämmerung. (https://en.wikipedia.org/wiki/Sigurd)
