History

Around 650 BBY (Before the Battle of Yavin), Darth Denarius of the Order of the Sith Lords came to power after killing his master. Darth Denarius lived during a time where the Jedi Order increased greatly, which he saw the need to decrease it. He decided that the Rule of Two, created by Darth Bane, was no longer necessary and went around the galaxy to find Force-sensitive beings to be his assassins.

After four years of searching for apprentices, he found three Force-sensitive beings: a human male named Jairus, a Togruta female named Nayah, and a Pantoran male named Kochi. Darth Denarius trained them in many arts: lightsaber combat, the Force, different types of blasters, and martial arts so that they can match the Jedi.

In 25 years, they were ready. However, when training the three, Darth Denarius took a big interest in Jairus. He trained him very well because Jairus was very intelligent and persuasive in words. Jairus was promoted to Darth Jairus, a Sith Lord. They were dispatched and disguised as bounty hunters around 625 BBY.

For five years, the three of them were successful in killing many Jedi, but Jairus caught the most attention by killing more Jedi than his companions and killed even political figures and famous Jedi. Because of his deeds, Jairus had one of the highest bounties in the Galactic Republic and was no longer considered a bounty hunter but a Jedi hunter. This made Kochi jealous of his fame and he plotted against him.

Even though it was restricted to have personal connections, Jairus and Nayah liked each other, but they kept it secret from their master. Because they loved each other so much, Jairus and Nayah exchanged gifts (a necklace for Nayah and a Sith armband to Jairus) to remember each other if one of them was to die. Without realizing it, Kochi knew of their relationship.

While Jairus was sent on a solo mission to take out an important leader on the planet of Pantora, Kochi snuck on his ship. While they were still over Orto Plutonia, Kochi attempted to surprise Jairus, but failed with Jairus sensing him. Jairus put the ship on auto-pilot and dueled Kochi. As they battled, they damaged the ship and Kochi was sucked out of the ship. Jairus, with his ship, disappeared into the snow and out of history. Kochi found a way off Orto Plutonia and went into exile to Pantora, his home planet, later gaining political power.

When Darth Denarius heard of Jairus's and Kochi's disappearance, he wanted to continue training Nayah, but she refused and left to her home planet of Shili, going into hiding. Darth Denarius then trained a new apprentice who later killed him around 580 BBY, becoming the next Dark Lord of the Sith.

Family Ties

This isn't Legends, I created these family ties to make the story more unique.

Nayah was the ancestor of Jedi apprentice Ahsoka Tano of Shili. When Jedi Master Plo Koon took Ahsoka into the Jedi temple, he never knew Ahsoka's ties to Nayah. Ahsoka still has Nayah's necklace.

Kochi was the ancestor of Senator Riyo Chuchi of Pantora. Riyo Chuchi knew that Kochi was once a senator for Pantora before, one reason why she ran for the office; but she never knew his dark past of being a Jedi hunter.
