The Warner System was a star system in the Verge of the Solarian League.
With a G9 primary, it was an anchor system of the Mannerheim-Warner Hyper Bridge with two habitable planets, Jacob and Wilhelm, two other planets, Aschenputtel and Rotkäppchen, and a single asteroid belt located less than a week's travel from the Sarduchi System and the Włocławek-Sarduchi Warp Bridge.
In the early 20th Century PD, it was home to a Frontier Fleet naval base and served as sector headquarters for the Office of Frontier Security. Additionally, the Jessyk Combine maintained a space station, Jessyk Station, at the Warner Terminus of the hyper bridge. (SI4,CS4)
