History
During the Dominion War, Septimus III was the headquarters of the Cardassian. The Klingon Empire landed fifteen divisions, wiping out the 500,000 men strong order. 

In 2389, Gul Madred, leader of the True Way, aquired the rights to several mineral rich planetoids and began building a large mining operation in the Septimus System.

In 2393, Madred contacts Lamat'Ukan of the Alpha Jem'Hadar. He agrees to send troops to protect the Gul's mines in the Septimus System to protect them from raiders. This begins the alliance between the Alpha Jem'Hadar and the True Way.
