The Darkstars were designed as an inter galactic police force during the absence of the Green Lantern Corp, and they included Donna Troy and Jon Stewart in their membership as well as much of the surviving Green Lanterns Corp. We've changed this quite a bit, because the idea of a organization created by the Controllers, the opposite organization of the Green Lantern's guardians, is a little bit too interesting not to explore further..
Instead, they were built for the Citadel, which we've built as a corrupt interplanetary government. We've deliberately brought about the end of the organization through the efforts of one of their own members, easily the most interesting original character designed for the team; Ferrin Colos. We've made him a lifelong government agent and dedicated protector who learned of the corruption of his own organization and who brought the group down, leading to his own imprisonment, which leads to him becoming a founding member of L.E.G.I.O.N.
This is an entirely original idea, but he's a great fit for Vril Dox's extra-governmental peacekeeping force. In the comics, Lady Styx eventually corrupts the Darkstars. We've reproduced this by having her forces kill Ferris and assimilating his technology into their weaponry.
