Walpurgis Night (ヴァルプルギスの夕べ Varupurugisu no Yūbe?), or also known as Night Party (夜会 Yakai?) and as well as referred to as a "Banquet of Strife", is a periodical feast held once every four years, on the year of the magic eclipse, at the Walpurgis Royal Academy of Machinart to select the premier puppeteer of its generation wherein young and talented mages vie with one another for supremacy, partaking in a series of blood soaked battles involving the clash of Machinart until there is only one person left standing; the winner, who then will be granted the title of the Wiseman by the Mage's Association.
In German tradition, Walpurgis Night (Walpurgisnacht in German) was a German festival celebrating Saint Walpurga before becoming associated with paganism and Satanism, as it was said to be a night for major gatherings of witches for spring celebrations.
