Ariada Cerulaen was the daughter of a Wroonian woman named Sylexa and Imperial Colonel Ios Meongula, conceived as part of an experiment by the Imperial Department of Redesign. After taking a number of Wroonians to serve as test subjects in a hidden laboratory on R'alla, Meongula used them to develop a virus that would alter the Wroonian genetic code and turn them into humans. By 26 ABY, Ariada and the rest of her team were fully-qualified and cleared to handle missions offworld, which was just as well, as the Yuuzhan Vong invasion had begun to threaten the entire galaxy by that point.
