Card Trivia:Sephylon, the Ultimate Timelord
- This card is named after the Sephirot, an alternate name for the Tree of Life, upon which the ten lower "Timelord" monsters are based. This was also referenced in the Yu-Gi-Oh! 5D's anime; when "Sephylon, the Ultimate Timelord" was about to be Summoned, a tree structure appeared with the other "Timelord" monsters depicted.
- This is the only "Timelord" monster whose artwork shows it from an angle rather than front on.
- This is one of only two "Timelord" monsters to not have an original ATK and DEF of 0, the other being "Sandaion, the Timelord".
- Despite its status as the higher level "Timelord", this is the only "Timelord" monster that does not have built-in protection from being destroyed, or an effect that prevents its controller taking battle damage from battles involving it. In the Yu-Gi-Oh! 5D's anime, it needs to banish one other "Timelord" monster to grant itself the built-in protection the other "Timelord" monsters have.
- Despite being in possession of the most powerful of the four Duelists from the future in the Yu-Gi-Oh! 5D's anime, this is the only one of their signature cards that is not Level 12, the other three being "T.G. Halberd Cannon", "Malefic Truth Dragon", and "Meklord Astro Mekanikle"; also, it is weaker than "Malefic Truth Dragon" in terms of ATK and DEF.
- This card's attack, "Akashic Storm", references "Akasha", the Sanskrit word meaning "aether", the basis and essence of all things in the material world, and the first material element created from the astral world. It is known as the "fifth element", the other four being WIND, FIRE, EARTH and WATER.
- This card, "Arcana Force EX - The Light Ruler", "Arcana Force EX - The Dark Ruler", "Odin, Father of the Aesir", and "Sandaion, the Timelord" have the highest ATK of all Fairy monsters in the OCG/TCG.
- In addition, this card, "The Light Ruler", "The Dark Ruler", and "Sandaion" also have the highest DEF of all Fairy monsters in the OCG/TCG.
