Having lost the war against the Curonians, exiled Prince Hading attacked Handwan's kingdom and eventually captured and ransomed him.
Hading used the ransom money to fund the liberation of his kingdom from the Swedish usurper.
Frotho infiltrated the city through trickery by disguising himself as a shieldmaiden deserter and then opening the gates from inside.
Rather than surrender his royal wealth, Handwan put his treasures onto a ship and scuttled it.
