The Dissidents' Ring is a ring that the dissidents use as a secret identification amongst themselves.
When Twinsen meets Johnny Rocket, he tells him to go to a dissident meeting, and gives him the ring. Twinsen must show the ring to the attendant in the Twinsonian Souvenir Shop to get to the meeting. Later, when Queen Astrid asks for a sign of good faith, Twinsen must show her the ring. After the Dissidents are discovered, if Twinsen shows the ring in the Twinsonian Souvenir Shop, the clerk will call guards to attack Twinsen.
