Kaeya stumbles out of the domain, set off-balance by the artificial wings sewn onto his back.

The wings twitch and spasm, the nerves alight with pain. He nearly falls as his sensitive wings beat erratically.

The worst part is he can feel the wings. They’re his and he can’t get rid of them without more pain.

An abyss herald had managed to catch him and pin him down long enough to stitch the awful things into his back and cast some sort of spell to get the bones and nerves to connect.
