The Viper Festival was an annual celebration held in Termina each year to honor the Acacia Dragoons and their continuing protection of El Nido and benevolent leadership. In Home World, the event terminated after the Dragoons disappeared in the Dead Sea. In Another World, the 100th festival neared in 1020 A.D.; festivities were to include a special performance by the Magical Dreamers. It was halted after Viper Manor was infiltrated and the Dragoons retreated to Fort Dragonia to defend against a possible Porre invasion. Porre's subsequent occupation probably laid the festival to rest for good.
