Darth Maladi provides Roan Fel with a container holding Omega Red.
Omega Red represents a lethal Sith poison, alchemically engineered by Darth Maladi circa 138 ABY. Its origins trace back to the New Republic's biological weapon known as Alpha Red. Diverging from its predecessor, which specifically targeted Yuuzhan Vong, Omega Red possessed the capacity to eliminate any species. Maladi proposed sharing the secrets of Omega Red with the Emperor in exile, Roan Fel, in return for sanctuary and the capture of Cade Skywalker. Fel consented to this arrangement, aiming to eradicate his adversary, Darth Krayt. However, it was revealed that the Sith were intentionally immune to the toxin, a deception orchestrated by Maladi and Krayt with the goal of decimating Coruscant. Fel nearly deployed the toxin, but Antares Draco intervened by assassinating him to stop its deployment.
