- In Nordic mythology, Valhalla is a great hall within Asgard, the home of the gods, where dead heroes were taken by Odin and the Valkyries, partying with the gods, and preparing to battle in Ragnarök.
- The name, "Hall of the Fallen", could be a reference to the "Darklords", as they are known in the OCG as the "Fallen Angels". The "Darklords" are also Fairy-Type monsters and can be used in combination with this card. It could also just reference that those who fall in battle (Einherjar) are brought here.
- This card has a Zombie-Type counterpart: "Call of the Mummy".
- Curiously the architectural style used in the design of the hall is Ancient Greek instead of Ancient Norse as one would expect since it is Valhalla.
- This card's ability to Special Summon Fairy-type monster from the Graveyard in the manga is instead given to the OCG/TCG version of "Athena" (who doesn't have this ability in the manga).
