A strength-granting potion could be created using Gretalax horn as its key ingredient. Long before the time of the High Republic Era, this substance was first conceived, and the method for its creation was written down in very old documents. In that period, the archaeologist Tapel, who wasn't a professional, unearthed these writings. This discovery prompted Layton Wyke to lead an expedition, including Tapel, to Loreth, a planet located in the Galactic Frontier, with the goal of obtaining Gretalax horn to produce the potion. After Ty Yorrick, a hunter of monsters and a one-time Jedi hired by Wyke to eliminate the Gretalax, learned about their real intentions, Wyke tried to kill her, thinking that her bones could be used instead of the horn in the potion.
