"There’s definitely something to be said for looking down on everything from on high. Wouldn’t you agree?" - —Cayenne's quote, Sen no Kiseki II
Duke Cayenne (カイエン公爵 Kaien Kōshaku) is an aristocrat who rules over the Lamar state in the western part of the Erebonian Empire, making him a prominent figure among the Four Great Noble Families. In possession of resources that far outstrip those of neighboring countries, he has a taste for the extravagant. He hired as his private army 'Zephyr', a group of top-tier light infantrymen that Xeno and Leonidas work for, as well as constructing in secret Pantagruel, an enormous flying battleship, all in an effort to get ready from the shadows for the then-impending civil war to be set off. With the Aristocratic Alliance having now captured the imperial capitol, he gets to work with Rufus Albarea in taking over the rest of the Erebonian Empire.
