Fourth Wing Characters
by Rebecca Yarros

Fourth Wing has a huge, tangled cast. Violet and Xaden anchor it, with Tairn and Andarna close behind. Around them are riders, dragons, professors, family, friends, and enemies. Some are marked rebels, some are loyal squadmates, and some just want Violet dead. It's a big ensemble, and it helps to know who matters and why.
This page breaks down who everyone is. You'll get their roles in the quadrant, dragon bonds, signets, key relationships, and how they change across the story. Expect protagonist and antagonist spotlights plus supporting riders, dragons, teachers, healers, and scribes.
