Joolushko Tunai Fenta Hovalis, or "Jool", is a young Interion woman of remarkable academic achievement – she scored "T"s in Genetics, Neuroscience, and Xenobiology, and has extensive knowledge of medicine, music, art, chemistry, universal cosmology, and gymnastics as well. Interions come from a peaceful star system, located far from both Peacekeeper and Scarran territory; before meeting Rygel, Jool had not known Hynerians or even Leviathans existed, though Sebaceans are familiar to her. Her hair blazes a fiery red when she is afraid and her screams melt metal at a molecular level (i.e. without heating it), an ability that has proven quite useful.
