Flag of the Younglings, from The Wheel of Time novels. Described in Chapter 1 of The Shadow Rising as consisting of "Gawyn’s sigil of the charging White Boar, but on a field of green rather than the red of Andor." The symbol also appears on the cloaks of the Younglings themselves, starting in the Prologue of Lord of Chaos.
