Golden shackles
Spoiler warning: Articles include story details through Episode 47 of the main campaign and all three episodes of Parental Advisory.

They radiate conjuration magic. Sefi's attempted teleportation fails while restrained, still expending its use under the session ruling; the key opens them. Their full limits and formal item name are not established.
Glenn reports a frightened seller associated with a hand tattoo who claimed they had restrained a planar traveler. Their later custody is inconsistent: one scene places them on a prisoner, another among possessions back in Beckinsdale.
