Danafor「ダナフォール Danafōru」 was a kingdom located within Britannia. It was once known to rival the Kingdom of Liones in terms of power, before being destroyed by Meliodas when he lost himself to his wrath.
Before its destruction, Danafor rivaled Liones in terms of military might and faced invasions from other countries of Britannia. Liz, a young knight from another country, led an attack on Danafor but was unsuccessful. She was sentenced to be executed, until Meliodas decided to rescue her, much to the anger of his fellow Holy Knights. Meliodas and Liz fell in love and the Holy Knights eventually warmed up to her. However, one day, Fraudrin appeared at the kingdom, nearly destroying it and killing many people, including Liz. When Meliodas saw the incident, he went berserk with the grief of his loved one's death, destroying all of Danafor with his demon powers, and nearly killing Fraudrin .
