The Battle of Parein II 4 was a heavy battle that took place during the first year of the Clone Wars.


In 22 BBY, General Grievous, the leader of the Separatist Droid Army, led his forces to attack the Republic opposition. During the conflict, Jedi Master Sannen tried to confront Grievous and avenge the Jedi victims that he slaughtered. However, his efforts to stop the deadly cyborg failed when a IG-100 MagnaGuard thrust an electrostaff through his throat, killing the Jedi General. After Sannen's death, Colonel Tyneir Renz and Commander Valin Draco were left in charge and continued to lead their battalions throughout the battle. However, as many clone troopers were slaughtered, Colonel Renz ordered a retreat while Valin Draco was badly injured and left for dead.

After the Republic left the planet, Valin Draco was thought to have been dead, but it is revealed that he survived. While on the planet, Valin was later hunted by a nighthunter and after a vicious fight, managed to subdue the beast and befriend it. After the Clone Wars ended in 19 BBY, Valin emerged during the time when the Great Jedi Purge happened and many Jedi were wiped out by the newly formed Galactic Empire. Rather than becoming a victim, Valin pledged his loyalty to the Empire and became an Inquisitor, falling to the dark side.
