Cadence (TCG)

 Cadence  was an air shūji, a secret body and sign language created by the Crane Clan to be used in courtly situations, when it could become advantageous for courtiers of the same clan to be able to communicate wordlessly. The Crane Clan were the masters and originators of Cadence, that was taught only to members of the Crane Clan. Over time, the Scorpion, Phoenix, and other clans had developed their own styles as well. Even the Mantis Minor Clan had such signals, used to communicate on the deck of a ship during storms.
