The original title for the series was called, " A Classic Era"
The first episode, "Birth of the Era" took seven months to fully complete while the other episodes were being worked on. Esteban Rodriguez had lost the editing files a week before the episode was supposed to premiere but was able to complete the editing two days before the date.
The Amadeus Legion uniforms were inspired by the famous red outfit worn by Wolfgang Amadeus Mozart in his self portrait.
