Sarpedion V

Sarpedion V is a planet in the Cardassian Union. It is the headquarters of the Twelfth Order and of the most heavily fortified locations in the Alpha Quadrant.

When Legate Korven arrived on Sarpedion V he took command of the Twelfth Order, a lowly regarded garrison, and turned it into one of the most effective of the Cardassian Guard. 

During the Dominion War, Chancellor Gowron planned to attack Sarpedion V. He planned to have General Martok take fifteen Vor'cha class ships in to soften the planet's defenses, although Marrok pointed out that this would barely scratch them. Ultimately, the fortified planet was not attacked, as Commander Worf challenged Gowron and made Martok Chancellor.
