The Glintara sector was a region of space in the Romulan Star Empire, bordering the Romulan Neutral Zone and Sector 30 (the Tarod Sector). The Cardassian-Romulan border ran through the Glintara sector.
In the forged holorecording created by Grathon Tolar in 2374, the planned Dominion invasion of Romulan space began with the advance of the 23rd Jem'Hadar Division through the Glintara sector, with the Cardassian Fourth Order protecting their flanks. The holographic Weyoun predicted that the Division would land on Romulus the following day. (DS9: "In the Pale Moonlight")
