Walpurgis Banquet

Walpurgis Banquet, Maoutachi no Utage (Warupurugisu) is a night where all the demon lords gather. After proposing it, the approval of three demon lords is needed to confirm and schedule it. A gathering of truly powerful individuals. Absentees have to be prepared to face severe consequences, as this is a covenant established between all the selfish demon lords. In the first place, these happen really rarely and are hardly mentioned in human literature.

The Walpurgis Banquet is typically associated with the beginning of a Great Holy Magic War. The last one being over a thousand years ago and resulted in myriad of casualties and great calamities. Thus, it is commonly known as the banquet that brings chaos and destruction into the lands.

Demon lords are only allowed to bring 2-3 subordinates. There is a reason for this restriction. A long time ago, there were demon lords who would bring over a hundred individuals to flaunt their power. Some had their countries reduced to ash so came seeking to be annihilated. So, they decided that they had to bring someone of at least low-class devil ranking. According to the now ruined demon lords, they had always brought high ranking devils, but no one can confirm that and such reports have been ignored. In order to prevent such foolish actions, they decided to limit the number of participants.

The seating order around the round table was decided based on the order in which one became demon lords.
