Sith Lightning.
It was a terrible thing, deadly, agonizing, and fueled by dark emotion. But it was something every Sith should know. The Kel Dor was not typically the type to share power with others, but he knew well enough how to counter the ability, and the raging swarm of Killiks that threatened the Empire was certainly a game changer. At the end of the day, Sol had grand aspirations for his own future, so why shoot the Empire he one day hoped to rule in the foot? No. They needed to be strong. Powerful. Untouchable. There could be no room for weakness.
Some that would arrive would come on their own transports, while shuttles would ferry the rest to the arena. Nearby landing pads, cracked with age, would still serve their purpose for the ships, and the trainees would descend the ramp to gaze into the sandy arena from the surrounding observation platforms. From there, they would be beckoned down sandstone steps by the Kel Dor, where he would await in the arena with a cold expression.
