During the extra-galactic Yuuzhan Vong's invasion of the galaxy between 25 and 29 ABY, the species attacked the Ord Janon system. Taking place at a point between 25 ABY and 26 ABY, the assault was preceded by the Battle of Birgis, in which the Yuuzhan Vong captured the planet Birgis from the New Republic with the aid of mercenary Mandalorian Protectors. After Birgis the Yuuzhan Vong split their forces to strike two targets, one of which traveled to the Ord Janon system .
Behind the scenes
The attack on the Ord Janon system was first shown in The Essential Atlas, a sourcebook released in 2009 and written by Daniel Wallace and Jason Fry. The Atlas included the attack in a map titled "Vector Prime and the Yuuzhan Vong advance" which showed the movements and conflicts of the various factions involved in the Yuuzhan Vong War, between 25 ABY and 26 ABY. The book gives no information on the outcome of the attack, but a separate map shows the Ord Janon system was under Yuuzhan Vong control by 26 ABY.
