Atlec (or Altec) was a planet located in the Omega Sagitta star system. Along with the people of Straleb, its population makes up the Coalition of Madena. War between the planets almost broke out in 2365, when the rogue freighter captain Thadiun Okona was accused of stealing the Straleb "Jewel of Thesia" for Yanar, the daughter of Atlec's leader Debin.
