Item from acotar-thorns-and-roses by
The inked brand on a fae's skin that seals a struck bargain, binding both parties under pain of agony.
A binding mark of magic that signifies a sworn oath between two beings, usually fae. It is both a contract and a brand, carrying the weight of the Cauldron's law. The mark is a permanent reminder of the promise made and the penalty for breaking it.
A tattoo-like mark that appears on the flesh of both parties the moment a bargain is sealed, often intricate in design and faintly luminous in the dark. The ink shifts and swirls as if alive, and the mark cannot be hidden or removed except by death or the bargain's fulfillment.
Also known as: Bargain Brand, Oath Mark, Promise Tattoo, Pact Sigil
