At the start of story development, the Sith world was called Korriban, but George Lucas preferred to change its name to Moraband. A world so ancient could have been known by different names in different eras.

George Lucas created Darth Bane during the development of the backstory for Episode I, though this episode is the first time he has appeared on screen. An earlier incarnation of Bane appeared in the comics and novels of the Expanded Universe, and this one nearly appeared as an apparition on Mortis in Season Three. The cutting of that sequence allowed for the character to undergo a redesign to define his canonical look, as well as allow the production to cast Mark Hamill as the voice of the legendary Sith.

Dooku's sparring uniform debuts in this episode, and not only afforded the Sith Lord a new look, but also helped aid the show's budget. With costly simulations throughout this episode -- the smoky Sith apparitions, Bane's fiery form, and the cloaks of Yoda, Sidious, and the Priestesses -- Dooku's cloak would have nudged the episode beyond its restrictions.

In the script, Sidious' incantation is said to be "Balc speech," and is written as follows: "Kintik hadzuska sutta chwituskak! Kintik hadzuska sutta chwituskak! Jiaasjen Jidai, jiassjen Jidai!"
