The red comet is a motif that develops The Illusion of Power, as various people interpret it largely as a portent of their success. Each person sees what they want or need to see in the comet, highlighting how power depends on appearance, perspective, and interpretation.

The comet’s significance is illustrated by the fact that it is the very first thing that appears in the novel’s prologue, as seen through the eyes of Maester Cressen. The fact that the comet is red resonates with the “red woman” the prologue introduces, Melisandre of Asshai. She interprets the comet as “dragonsbreath.” One of Joffrey’s knights sees the comet as a sign to “herald Joffrey’s ascent to the throne” and defeat the other kings (38-39). When Theon arrives at Pyke, his uncle Aeron calls it a “rising tide” brought by their deity, the Drowned God. Daenerys views the comet as a sign from the gods “to show [her] the way” (187). Each of these interpretations validates Varys’ insight that power is arbitrary, and people will find it wherever they believe it resides. By calling the comet a sign of their favor, these characters reveal how illusory their power really is.
