Willm Lywin was a male Duinuogwuin Jedi Master. During the first four hundred years of his life, Lywin was part of a group of "living snubfighters" which escorted a praxeum ship. He was one of the founders of the Teyan Praxeum, where he guarded the pathway to the Cave of Truth for six hundred years. Vici Ramunee once encountered him when she traveled to the Cave, and found the old dragon both friendly and funny.
