The Binding was the closing moment of the Last War. It was a scheme concocted by Doremil to end the conflict forever and protect the Children from the rivalries of the Kembar.
It began when Doremil sundered their very being, sacrificing themselves to the Void. Thereafter, by mechanics still unknown to the Children, the Kembar were banished from the Earth to parts unknown, able to commune with the world’s inhabitants only through the faintest of dreams and signs.
