In Trails in the Sky the 3rd, Star Door 14: "Phantasmal Blaze", Oathbreaker expresses his surprise over Georg Weissmann's death following the conclusion Gospel Plan and inquires after the assassin's name. He then criticises the Second Anguis for "not even [mourning Leonhardt's] loss for more than a second before setting [her] eyes on a new guy".
- The name of Thousand Oathbreaker literally translates as 'one who has broken a thousand commandments'.
- Thousand Oathbreaker's dialogue lines are written in a distinctive style in Japanese. His vowels are lengthened playfully as "なァ" or "ねェ", a trait he shares with Lechter Arundel.
- His voice actor in Trails in the Sky the 3rd Evolution, Keisuke Baba, also voiced Carl Regnitz in Trails of Cold Steel I, II, III, and IV and Dogi in Ys Seven.
- ↑ When Arianrhod enters the Celestial Globe in Ao no Kiseki, Chapter 3: "Flux: Carnival of Beasts", she updates the other Anguis that "the rest will be left to Oathbreaker"[JP 1] before turning her attention to Crossbell. When she herself starts her activities in Erebonia from Trails of Cold Steel III, Chapter 3: "Pulse of Steel" onward, she states that "Oathbreaker and Mariabell have taken on the responsibility for Arteria".[JP 2]
