Lucem, a species of humanoids, inhabited the galaxy. These beings were recognized by their almost see-through, light-colored skin, white hair, and peculiar eyes. Their eyes were entirely black, featuring numerous tiny white pupils. Uniquely, the Lucem possessed the ability to manipulate these multiple pupils, shifting them within their eyes as a defensive tactic to induce dizziness in those they considered dangerous.
The Lucem gained recognition throughout the galaxy for their skill as speakers, songwriters, and dramatists, with their creations preserved within the Jedi Archives. Records indicate that at least a couple of Lucem held membership in the Jedi Order, including the former Padawan known as Ruu.
