In the forged holo-recording created by Grathon Tolar in 2374, the planned Dominion invasion of Romulan space involved the advance of the 23rd Jem'Hadar Division through the Glintara sector, with the Cardassian Fourth Order protecting their flank. The holographic Weyoun predicted that the division would land on Romulus the following day. (DS9: "In the Pale Moonlight")
According to Star Trek: Star Charts (p. 66) and Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", pp. 32-33; "Federation Historical Highlights, 2161-2385"), the Glintara sector (Sector 31) was located in the Beta Quadrant. Within this sector, there was a star system named Glintara, which this sector might possibly be named after. This was a binary system with a pair of K-class stars.
