Septimus III

Septimus III was a planet in the Cardassian Union.

While trying to guess the location of the planned Federation Alliance invasion of Union, Nikki Whitechapel pointed out that their prediction of the Dorvan sector could be wildly incorrect and that they might be heading for Semptimus III.

In 2375, the Klingons invaded the planet and slaughtered the Eleventh Order, over 500,000 Cardassians.
