Vortex (episode)

===Production===
*The making of this episode was extremely costly. It was produced amongst a few other installments that were also expensive to produce. (''[[Captains' Logs Supplemental - The Unauthorized Guide to the New Trek Voyages]]'', p. 33)
*Originally, the Miradorn throat was designed with a loose flap of skin hanging down over the Adam's apple. Costume Designer [[Robert Blackman]] wanted to use a necklace as part of the Miradorn costume, but Make-Up Supervisor [[Michael Westmore]] felt that placing a necklace over the flap of skin would render it useless and spoil the effect. As such, it was decided to let the necklace run under the flap of skin, and glue the skin down at the bottom, so it was no longer loose. (''[[Michael Westmore's Aliens]]: Season One'', [[DS9 Season 1 DVD]], special feature)
*The exterior visuals of the [[Chamra Vortex]] were re-used shots of the [[Mutara Nebula]] from {{film|2}}, recolored slightly and flipped upside-down.
