Ywain
Son of King Urien, listed among the noble knights at Arthur's court in Sir Gawain and the Green Knight.
Ywain appears in Sir Gawain and the Green Knight as a knight of Arthur's court and the son of King Urien. He is listed among the noble company present at the court: "Ywain, King Urien's son, sat at the other side alone" (Sir Gawain and the Green Knight, Part I: Of the noble knights there present). He also appears in a later gathering alongside Erec, Dodinel le Sauvage, Launcelot, Lionel, Lucan the Good, Bors, Bedivere, and Mador de la Porte (Sir Gawain and the Green Knight, Part II: Sir Gawain bethinks him of his covenant).
The two attestations from Sir Gawain and the Green Knight place Ywain within the broader Arthurian court but give him no individual action. In Part I, the detail that he "sat at the other side alone" distinguishes him spatially from the other knights, though the significance of his solitary seating is not explained (Sir Gawain and the Green Knight, Part I). In Part II, he is simply one name in a catalogue of assembled knights. Together, the attestations confirm his standing as a recognized member of Arthur's inner circle, but this source offers no narrative role for him beyond presence.
