Duel on Nirakos

The Duel on Nirakos was a battle that took place as part of the Galactic Empire's extented Jedi Purge.

Prelude
Kira Cereza was a Jedi Master during the Clone Wars. In 19 BBY, she would discover two force sensitive children on the planet Torano II, Ral Silber and Ren Silber, and would take them with her to be trained as Jedi. However, on her way back, Order 66 was executed and the Jedi Purge began. Sensing the dramatic shift in the Force, Master Cereza instead fled to the Outer Rim planet of Nirakos to train the two younglings on her own, in the hopes of one day helping to restore the Jedi Order.

In 4 BBY, Kira Cereza would eventually be tracked down by the Galactic Empire, who would send the Eleventh Brother, an Imperial Inquisitor, to eliminate her.

The Eleventh Brother, as well as 4 Purge Troopers and 8 Stormtroopers, arrived on the planet at the village where Master Cereza was hiding with Ral and Ren. The Eleventh Brother ordered the Stormtroopers under his command to raze the village in order to lure Master Cereza out of hiding, which succeeded. Master Cereza cut down the Stormtroopers with ease, and summarily bested the Purge Troopers as well, though with a bit more effort, before turning to face the Inquisitor himself.

The Duel
The duel first involved Jedi Master Kira Cereza engaging the Eleventh Brother in one-on-one combat. The duel began with both combatants being evenly matched. However, Master Cereza, having fought multiple other combatants beforehand, and being unused to a full-on lightsaber duel in her years of exile, began to lose her ground to the Eleventh Brother. This was exacerbated when the Inquisitor activated the second blade of his lightsaber, and utilized the spinning mechanism of the weapon in order to quickly overpower the Jedi Master. It was at this point that Ren Silber, who had been hiding nearby with his older sister Ral, jumped out to try to save his master, though Cereza was cut down before he could stop the Inquisitor from delivering the final blow.

With the two other Force sensitives now discovered, the Inquisitor then turned his blade on the young pair, with Ral Silber stepping forward to defend her brother, activating her lightsaber to engage the Inquisitor. This part of the duel was much shorter, as Ral had never fought in a real lightsaber duel before. Though she fought her best, attempting to utilize the skills that her master had passed down to her, she was defeated as well, and her brother could only watch as he toyed with her and eventually struck her down. Ren then called his sister's lightsaber to his hand, activating it and engaging the Eleventh Brother in rage.

The third engagement of the duel began in Ren's favor, with his naturally high affinity with the Force allowing him to overpower the Eleventh Brother, especially as he was being fueled by the Dark Side of the Force. Taken aback by the sudden display of power, the Eleventh Brother worked to regain his composure, studying Ren's relentless but unfocused attacks and finding an opening. Using the spin of his double bladed lightsaber, he disarmed Ren of his weapon and knocked him to the ground. Before he could finish the Padawan, however, he was struck by a fierce storm of Force Lightning conjured by Ren, which knocked him back and severely injured him. With the Eleventh Brother on the ground, unable to move, Ren reclaimed his sister's lightsaber and with it finished off the Eleventh Brother on the ground.

Aftermath
After the duel, Ren realized that the Empire would only send more to finish him off if he stayed, thereby putting what remained of his home in even greater danger. Ren would take the Eleventh Brother's lightsaber with him as he procured a ship to take him off world, beginning his journey into the wide Galaxy.
