Manticores

Manticores are significant in the passage as the source of the venom that is killing Ser Gregor. Their presence is not shown directly; instead, they enter the narrative through Qyburn’s examination of the poison on the Viper’s spear, turning an exotic creature into the hidden agent behind one of the court’s most gruesome medical mysteries.

The Venom’s Origin

Qyburn identifies the poison as manticore venom from the east and expresses complete confidence in his conclusion. His claim conflicts with Pycelle’s account that manticore venom kills as soon as it reaches the heart, a disagreement that makes the creature’s venom central to the question of why Ser Gregor remains alive. The reference therefore establishes manticores through a disputed piece of learned knowledge rather than through appearance or behavior.

A Delayed Death

Qyburn explains that the venom has somehow been thickened, causing Ser Gregor’s death to unfold slowly instead of immediately. He remains certain that the knight is dying from the venom, but its altered consistency has drawn out the process and left him in severe agony. The manticore’s poison consequently becomes more than a weapon of instant murder: in this altered form, it produces a prolonged physical ruin.

Monstrous Physical Consequences

The effects attributed to the venom are described in stark bodily detail. Ser Gregor’s veins have turned black from head to heel, his urine is clouded with pus, and the venom has eaten a hole in his side as large as Qyburn’s fist. He suffers blinding headaches and repeatedly drinks milk of the poppy to dull them, while his screams disturb both Tommen and the queen. Manticores thus remain unseen, yet their violence is made visible through the transformation of a living human body.

Uncertainty and Fear

The cause of the venom’s unusual behavior remains uncertain. Qyburn suggests that the poison may have been adulterated, though he admits that weakening a poison generally reduces its potency; he also raises the possibility of a spell. This hesitation prevents the manticore venom from receiving a wholly natural explanation. Whether its lethal persistence comes from deliberate preparation or something more mysterious, the result is the same: Ser Gregor’s survival becomes a spectacle of suffering, and the eastern creature associated with the venom acquires an aura of remote, barely understood danger.
