The glamor
The glamor is a form of sorcerous illusion practiced by Melisandre of Asshai, a priestess of R'hllor, the Lord of Light. It is a tool of deception that allows its user to alter a person's appearance, making them seem to be someone else entirely. Melisandre employs this art to disguise Mance Rayder as the wildling raider Rattleshirt, thereby saving the King-Beyond-the-Wall from execution and secretly deploying him on a mission beyond the Wall. The glamor is not a simple trick but a complex weaving of light, shadow, and desire, and its most powerful manifestations require physical objects that carry the memory of the person being impersonated.
Nature and Mechanism
Melisandre describes the glamor as a form of 'seeming' or 'illusion' that works by draping a person's shadow about another like a cloak. 'Call it what you will. Glamor, seeming, illusion. R'hllor is Lord of Light, Jon Snow, and it is given to his servants to weave with it, as others weave with thread,' she explains. The strongest glamors are built from physical objects associated with the person being impersonated. 'The bones help. The bones remember. The strongest glamors are built of such things. A dead man's boots, a hank of hair, a bag of fingerbones. With whispered words and prayer, a man's shadow can be drawn forth from such and draped about another like a cloak. The wearer's essence does not change, only his seeming.' This reliance on material anchors distinguishes the glamor from mere mummery or simple sorcerous disguise; it requires a tangible connection to the original person.
The Glamor on Mance Rayder
Melisandre's most significant use of the glamor is to disguise Mance Rayder as the wildling raider Rattleshirt. After Stannis Baratheon captures Mance and sentences him to death by fire, Melisandre secretly substitutes the Lord of Bones for the King-Beyond-the-Wall. She places a ruby-studded iron cuff on Mance's wrist, which serves as the focus for the illusion. 'The ruby on the wildling's wrist darkened, and the wisps of light and shadow around him writhed and faded. The bones remained—the rattling ribs, the claws and teeth along his arms and shoulders, the great yellowed collarbone across his shoulders. The broken giant's skull remained a broken giant's skull, yellowed and cracked, grinning its stained and savage grin. But the widow's peak dissolved. The brown mustache, the knobby chin, the sallow yellowed flesh and small dark eyes, all melted. Grey fingers crept through long brown hair. Laugh lines appeared at the corners of his mouth. All at once he was bigger than before, broader in the chest and shoulders, long-legged and lean, his face clean-shaved and windburnt.' The illusion is so complete that Jon Snow, who knows Mance well, is utterly shocked when Melisandre reveals the truth. 'Jon Snow's grey eyes grew wider. "Mance?" "Lord Snow." Mance Rayder did not smile.' The glamor allows Mance to survive the execution that the world believes killed him, while the real Rattleshirt dies in his place.
Consequences and Significance
The glamor's success has profound consequences. By disguising Mance as Rattleshirt, Melisandre not only saves his life but also provides Stannis with a plausible public execution that satisfies the demands of law and justice. The ruse is so effective that even the wildlings believe their king is dead, which helps to break their resistance and force them to submit to Stannis's authority. More importantly, the glamor enables Mance to undertake a secret mission: to travel north of the Wall and find Arya Stark, who is believed to be fleeing from her forced marriage to Ramsay Bolton. Melisandre tells Jon Snow, 'There he stands, Lord Snow. Arya's deliverance. A gift from the Lord of Light... and me.' The glamor thus becomes a key instrument in Melisandre's broader scheme to win Jon Snow's trust and influence the course of events in the North. The art itself, however, is not without cost. Melisandre admits that maintaining the illusion is difficult and painful, though she conceals the effort to make the sorcery appear effortless, knowing that 'the more effortless the sorcery appears, the more men fear the sorcerer.'
