Card Trivia:Magical Citadel of Endymion
- The "Endymion" cards are named after the Greek mythological figure of Endymion who was beloved by the moon goddess Selene and put to sleep forever.
- The Citadel has a striking similarities to the town of Geffen in the online RPG game Ragnarok Online. Both have a circular perimeter, a tall tower in the center, architectural buildings, and most of all, both are a town of spellcasters (mages and wizards in Ragnarok).
- "Citadel" appears in the artwork of "Fusion Recycling Plant" and "Mythical Institution".
