Card Trivia:Unholy Knight Ariel


 * This card's name is based off Roy Khan (former vocalist of Conception and Kamelot) and his role as Ariel on both the 6th and 7th (concept) albums of Kamelot, Epica and The Black Halo.


 * This card being Level 10 is a reference to the last album produced by Kamelot with Khan as the vocalist (the 10th, Poetry for the Poisoned), and its requirements of sending a Level 6 and a Level 7 monsters to the Graveyard in order to be Summoned references the aforementioned albums Epica and The Black Halo.


 * This card's effect of revealing the opponent's hand represents the Ariel's will to discover the universal truth, and its effect of Summoning a Fiend-Type monster instead of being destroyed references the descent of Mephisto to Ariel.
