A world of perpetual night resided within the galaxy, characterized by ashen swamp landscapes perpetually shrouded in a haze of electric mist. Darth Caldoth, a Sith Lord, journeyed with Ry Nymbis, his apprentice, to this nocturnal world with the explicit purpose of having him pursue, and ultimately kill, a knight in order to seize their lightsaber. Nymbis fulfilled this task, and subsequently employed the captured saber to create a lightsaber uniquely his own.
