Faebane

A poison that chokes magic at its source, rendering even the most powerful High Fae mortal-weak.

Also known as: Fae's Bane, The Choker, Wall-weed, Green Death, Mortal's Mercy

What They Know

Faebane is harvested from a thorny, low-growing plant that thrives only in the shadow of the Wall, where the magic of Prythian meets the iron-rich soil of the mortal lands.
The poison works by binding to the magical essence in a faerie's blood, forming a crystalline lattice that blocks the flow of power — the stronger the fae, the more agonizing the effect.
Mortal queens and rebel cells have stockpiled faebane for centuries, knowing it is the only thing that can level the field between a human and an immortal.
The King of Hybern's agents have been known to trade in faebane, using it to control or eliminate rivals who might challenge his authority.
In the Night Court, possession of faebane is punishable by death — Rhysand's decree, unbroken since the War, for the poison was used to torture fae Under the Mountain.
