This almost invisible 3ft strand of silk is unbreakable and easily hidden. Often used as a garrote, this cord won't cut its owner's hands during use and will untie itself from anything and slither / float (no matter the distance and even across planes) back to its owner with a whispered 'Cordelia.'

For an owner to become imprinted upon the cord he must stitch his mouth shut with the Cord of Cordelia at midnight during a full moon and only remove the Cord after the next midnight.
