A skirmish at the planet Helska IV in 25 ABY marked the beginning of the Yuuzhan Vong War. Arriving at the Helska system, unaware of the Yuuzhan Vong presence, Kyp Durron and his Dozen-and-Two Avengers headed into the Battle of Helska.
Leaving Lando Calrissian's mining operation in a asteroid field, Durron and his Avengers checked on a buoy set up to monitor local traffic and help in catching smugglers. On the holo, Durron noticed a Spacecaster-class shuttle heading for the Helska system, and decided to investigate.
Arriving at the Helska system, they found Helska-4, a barren ice world. Unbeknownst to the Avengers, a Yuuzhan Vong worldship had landed on the planet and set up a sizable base. When they ventured closer to the planet, they encountered small, asteroid-like objects grouping near them. Without warning, the asteroids opened fire on the Avengers, who realized that the objects were not asteroids at all, but a kind of starfighter analog. The Avengers fought off the enemy starfighters (later dubbed coralskippers), and were faring well until the Yuuzhan Vong began using dovin basals to strip the Avengers' fighters of their shields. Without their shields, the Avengers were quickly decimated. Remaining fighters tried to escape but they were attacked by Grutchins. Miko Reglia crashed onto Helska and died not long after, and Durron and an unknown A-wing pilot made blind jumps into hyperspace, though the latter's craft likely exploded from its overpowered engines before it could activate the hyperdrive. Kyp Durron was the only survivor of the battle.
