During the Yuuzhan Vong species's intergalactic invasion of the galaxy that occurred from 25 ABY to 29 ABY, the Circumtore system in Hutt Space was targeted by the Vong. The battle transpired between the years of 26 ABY and 27 ABY; the Vong reached the system via the Gamor Run hyperlane, coming from a previous engagement in the Rorak system. Following this assault, the Vong proceeded along the Hollastin Run Hyperlane and attacked the Hollastin system.
The reference book The Essential Atlas, authored by Jason Fry and Daniel Wallace and released in 2009, was the first place the Circumtore system attack was depicted. While the book's text doesn't mention the attack, it appears on a map illustrating conflicts across the galaxy from 26 ABY to 27 ABY during the Yuuzhan Vong War, labeled as "collapse of the Core". The attack's outcome isn't detailed, but another map indicates that Circumtore was under Vong dominion by 27 ABY.
