Dargol was an experimental substance developed by Linea in her attempts to create a "Fountain of Youth". She hoped to eventually use this chemical on herself, but first tested it on two Vyan test subjects. Not realizing the scope of her project, the Dargol wiped out the entire infant population of Vyus and regressed the older individuals into much younger people, wiping them of their memories, something the Vyans would later call the vorlix. Linea herself was exposed to the substance.
