The White Ribbon is a traditional symbol of truce in Arad Doman. If one person offers the White Ribbon and his opponents accept it, they will be bound by oaths on their souls and hopes of salvation not to draw a weapon against each other or shed blood for three days.
The White Ribbon was most recently offered by Rodel Ituralde to the various Dragonsworn lords and Taraboner soldiers on Almoth Plain and in Arad Doman. Ituralde believed his order to do so came from King Alsalam, but it was actually sent by Graendal. The Dragonsworn and Taraboners accepted the White Ribbon and Ituralde convinced them to make a truce to battle the Seanchan.
