Keiran Valn, a Jedi Knight of the male persuasion, existed in the era of the Old Republic. During a feast hosted by his kin on his native planet of Alderaan, Valn met his end through a successful poisoning. Despite his status as a Jedi Knight, Valn succumbed to the lethal toxin and passed away, becoming one with the Force. The demise of a member of their Order's ranks deeply disturbed the Jedi Council, and initial inquiries indicated that the poison employed was a substance extracted from the water-based flora known as green glie, originating from the world of Naboo.
