Card Trivia:Darkness
- Nightshroud and the World of Darkness appear in this card's artwork.
- This card is based on the World of Darkness in the Yu-Gi-Oh! GX anime, which served as Nightshroud's realm of origin.
- This card's effect to Set "Zero", "Infinity", and the "Darkness" Continuous Trap Cards is based on how Yusuke Fujiwara (while possessed by Nightshroud) described the World of Darkness as both "zero" and an "infinite world" in Yu-Gi-Oh! GX episode 175: "Battle Royal! Judai VS Johan VS Fujiwara".
- This is the only Field Spell Card to be shown in face-down position in the anime.
- In the Yu-Gi-Oh! GX anime, when Nightshroud activated this card, it turned his white wings black, which he used as his Duel Disk.
