- This card is based on the Tarot card, The High Priestess, the second of the Major Arcana.
- This card's Japanese name comes from the Swiss Troccas tarot deck, which uses Juno or Junon in place of The High Priestess card.
- Another monster, "Lady of Faith", is also based on The High Priestess tarot card.
- "Spellbook of Wisdom" appears in this card's artwork, and vice versa.
- This card could be considered a counterpart of "Prophecy Destroyer"; both cards can be Special Summoned if at least 3 "Spellbook" cards are in the right place ("High Priestess" requires them to be revealed in the hand, and "Destroyer" requires them to be banished from the Graveyard). Both cards also have 2500 ATK.
