This song was sang in the Age of Legends by Nym, Ogier, Da'shain Aiel and Aes Sedai to help plants to grow and to increase harvest. The song may be essential to growing of Chora trees. During the breaking of the world, this song was forgotten even by Aiel and in time became goal for Tuatha´an to find. It has been sung by Rand in front of Tuon as a sign at their meeting. It seems Rand knew it as Lews Therin and inherited this memory,as all others,in the last chapter of the Towers of Midnight.
