Faebane

A poison brewed from faebane root that chokes the magic from a faerie's blood, leaving them mortal-weak and defenseless.

Also known as: Faebane poison, Fae-killer, Magic-choker, Root of silence

What They Know

Faebane is derived from the root of the faebane plant, which thrives only where the Wall's magic meets mortal soil.
The King of Hybern's alchemists perfected the brewing process, making it potent enough to incapacitate a High Lord for hours.
Iron filings are often mixed into faebane to double its effect, as iron burns fae skin and the poison chokes their magic.
A single drop on a wound can render a faerie powerless for a day; a full draught can kill.
The mortal queens south of the Wall pay handsomely for faebane, hoarding it as their only defense against fae incursions.
