One of the three Dread Trove relics — the crown that compels the mind to obey
The Crown
A large crown of golden spikes, Made by the Cauldron in ancient times — one third of the Dread Trove, and the most insidious of the three.
Where the Mask raises the dead and the Harp opens any door, the Crown takes the mind: it compels its victims to act against their own will, fully conscious of the horror and unable to stop. It can override even strong mental shields. Per Amren, it must be near a mind to first take hold.

What it is
The relic
The Crown is a large crown forged of golden spikes — one of three artifacts that make up the Dread Trove, each Made by the Cauldron in ancient times. Of the three Trove objects, it is the one worn on the head. In Nesta's vision of Queen Briallyn enthroned, the spiked golden crown rests on the crone's head, an image of gold metal, spiked form, and radiating menace.
What it does
Mind control
The Crown grants mind control. Amren, briefing Nesta on the Dread Trove, explains it could make your enemies do your bidding — even force a parent to act against their own child, aware of the horror but unable to stop. The terror of the Crown is not brute force but subversion: the victim remains fully conscious while their body obeys the wearer's will. It can override even strong mental shields — a grave threat in a world where daemati like Rhysand depend on mental defense. Its limitation, per Amren, is proximity: the Crown must be near a mind to first take hold, which is why Briallyn needed agents close to her targets.
Origin
Cauldron-Made
The Crown is one of three Dread Trove relics Made by the Cauldron. The Trove comprises the Mask (which raises and commands the dead, molded from a long-forgotten king's face), the Harp (which opens any door and moves its player through space), and the Crown (which controls minds). Together the three objects historically conferred near-limitless power, and possessing the Trove could also help locate the remnants of the Cauldron itself — which is what made it worth hunting.
Who held it
Briallyn to Nesta
Queen Briallyn — one of the mortal queens, turned into a withered fae crone by the Cauldron as punishment after Nesta took power from it during her own Making — allied with the death-lord Koschei and sought the Dread Trove to invade Prythian, find the Cauldron's remains, and take her revenge. With the Crown she seized control of others, including Autumn Court soldiers. The Crown passes to Nesta when Nesta Unmakes Briallyn in the climactic battle — the Crown survives the destruction of its wielder — completing Nesta's acquisition of the full Trove. Afterward the objects are secured by the Night Court.
The Crown in action
"Kill"
At the climax of A Court of Silver Flames, Briallyn uses the Crown to seize control of Cassian, demanding Nesta surrender the Trove or lose her mate. When Nesta does not comply, Briallyn commands "Kill" — but names no target. Cassian, fighting the compulsion through his love for Nesta, turns his dagger toward his own chest rather than harm his mate, and struggles to warn her to run. The scene confirms the Crown's mechanics from Amren's briefing: a controlled victim becomes a puppet who obeys literal orders — yet extraordinary willpower and the ambiguity of an unspecified target let Cassian redirect the kill-order onto himself. Compulsion absolute; love, just barely, a loophole.

The Dread Trove
The Crown is one of three Cauldron-Made objects that together form the Dread Trove. Each wields a different dominion — over the dead, over doors, and over the mind.
