The Battle of Telos was an event involving Clan Naga Sadow and the Yuuzhan Vong at Telos. The Clan's objective was to break the Far Outsiders hold on the Hydian Way.
The Dlarit Navy was sent in to divert the enemy fleet at Telos while the Final Way deployed a team of Dark Jedi to take out the Yuuzhan Vong worldship stationed there.
This was the first major battle between the Clan and the Vong since the Battle of Antei. It ended with the destruction of the worldship and the arrival of Grand Master Jedgar Paladin
