Three off-world judges appear inside the ballroom through a projection that gives them strange auras, light touch, scent, and remote service.
The panel consists of Empress D'Nadia, a tall thin soother, and an upward-mouthed jello-like alien. Their goodwill projection is convincing enough to smell and touch lightly but does not place their real bodies in the castle.
An ethereal hand appears before D'Nadia, passes her a drink, and vanishes, showing that staff or technology outside the visible overlay can serve them. Signet immediately recognizes their auras differ from every in-world being and treats that as evidence for Carl's claims about off-world control.

The judges provide Signet with observable seams between her world and the outside production.
