Otto Steinroth
From Warhammer - The Old World - Lexicanum
Otto Steinroth was also known as the Red Pirate of Marienburg. [1a]
History
In 2344 IC, he managed to find a way through the mists that guarded the coast of Ulthuan, sacking the High Elf city of Sardenath. [1a]
Loaded with plunder, he set course for home, unaware that he was being pursued by the fleet of the Sea Lord Aislinn. When they began to dock at the great city, the High Elf fleet struck, concealed from the formidable defences of the port by a magical fog. [1a]
Otto himself was cut down by the sword of the Sea Lord. [1a]
