- This card's name and activating condition involving "Dark Magician" monsters possibly allude to the Korean MMORPG Online Game of the same name. Concepts of dark magic are recurrent in RPG games, which presumably inspired this card.
- In Norse mythology, Ragnarök is a series of future events that eliminates the world's occupants, before renewing it and repopulating it. Befitting this, this spell card is able to affect a God Card, which is normally impervious to magic, but as Ragnarök is the "twilight of the gods", the spell destroyed no one less but "The Winged Dragon of Ra".
- Figures from Norse mythology appear in this card's artwork, including Odin, who wields his spear Gungnir while riding his Sleipnir opposing the wolf Fenrir, Thor, who opposes the world serpent Jörmungandr and wields his hammer, Mjölnir, and Freyja opposing the fire giant Surtr. Also, the tree which appears in the artwork could be Yggdrasil.
- This card's written effect states that it destroys the opponent's monsters; therefore, it is uncertain how it was able to remove The Winged Dragon of Ra from Yami Marik's field, as Ra cannot be destroyed by card effects.
- While Magical Dimension is used in the manga and OCG/TCG, that card's effect is added to this card in the anime though it was revamped.
