"Illuminated" is the fourth episode of Star Darlings.
In the Illumination Library, Vega reveals that she has put together an "Odd Wall" of all the strange things... and people that could be behind this negative energy.
Vega continues to do research on the causes of negative energy affecting Starland. She adds a few possible suspects to the Odd Wall on her Star-Zap. Two being Vivica, for her negative attitude, and Professor Ursa, for her hatred of Wishlings. The third being Scarlet presumably due to her rebellious attitude. Vega soon discovers a Holo-Book on Negetite, a mineral capable of harnessing strong negative energy, raising their suspicions.
