Allison is an adventure series set in a world containing one continent (extending roughly from the Equator to 60 degrees North latitude) which is divided down the center by a towering mountain range and a huge river. The industry and technology of the world are roughly equivalent to Europe in the 1930s. Due to the geography, two cultures developed on either side of the divide, and at the time the story begins, the cultures have been at war on and off for hundreds of years. The east side of the world is known as , though formally the region's name is the Roxcheanuk Confederation. The entire region comprises sixteen countries which all speak a common language. The west side is known as , though formally the region's name is the Allied Kingdoms of Bezel Iltoa. The region comprises the two kingdoms of Bezel and Iltoa which both serve to bring together a small number of countries under a common language different than that of the eastern region. There are far more blond-haired people in the West than in the East.
At the beginning of the first novel, Allison, a pilot in the Roxche Air Force, has come to visit her childhood friend Wilhelm ("Wil" for short), who has remained at school over his summer break to continue his studies. While traveling in the countryside near the school, the two encounter an old man well known to Wil's schoolmates as a teller of tall tales. Nevertheless, he captures their interest with his talk about a "treasure" which, if found, is said to be able to put an end to the war.
(Note: as a resident of Sou Beil, "Carr" is his surname and "Benedict" is his personal name.)
