Ohop was a star system, situated somewhere in the space of the galaxy's Alpha or Beta Quadrants. The system was along Zonek Karle's route to Terok Nor, and the Founder who was with him suggested cutting through to make the journey end faster. Karle said they were sure to be caught by Starfleet if they went through that system. (ST - Tales of the Dominion War short story: "Night of the Vulture")
