I Am Coming to Rescue the Princess

The story goes that honoria sent a messenger to find the great attila the hun and ask him for help. Enclosed with her note begging to be rescued from the prospect of a boring life with a boring man, was one of honoria's rings. Atilla responded by declaring himself ready to marry honoria and demanding, oh, let's say, half the western empire as a dowry. When the imperial court scoffed at this demand, attila began to prepare an invasion - which is completely insane.
