Rylca, a remedy for the krytos virus, was created through the cultivation of specific bacta components within a setting enhanced by ryll kor. This cure was the brainchild of Qlaern Hirf, a verachen from the Vratix, who formulated it for the New Republic in 7 ABY. Its purpose was to combat the krytos epidemic that erupted on Coruscant. A significant producer of rylca was Alderaan Biotics.
