- The castle shown in this card's artwork is very similar to Pegasus' castle in Duelist Kingdom, with an identical balcony and front gate.
- The fortress that appears in this card's artwork seem be in "Royal Decree", "Royal Surrender" and "Rock Bombardment".
- The king overlooking his fortress is like the one that appear in "Conscription".
- The king (and the castle) featured in "Royal Decree" is always retraced in a Trap Card, or a Trap Card that has something to do with other Trap Cards, like "Royal Decree" and "Royal Surrender". Similarly, the king that appear in "Imperial Order" and "Spell-Stopping Statute" is retraced in a Trap Card that has something to do with Spell Cards.
