other treasure-hunters think that the aude department plays an important role. they focus on the 470 illustration and try to find the good light from roncevaux. phonetic-similarity links the aude department with the aube river, and (because 'aube' is the french word for 'dawn') with the sunrise, and so the treasure-hunters use the aude department (which is also the 11th french department) as the targeted light in 470. they use historical information about roncevaux (which is close to the aude department) to complete it and find the zone.
