The Visonians (endonym Visakoje) are a Galeanic people of the Ichtonic subgroup native to Southeastern Levropia. With a population of around 11 million in the mid-20th century, they are the largest Ichtonic ethnic group in the world. They make up the Visonian nation, which forms the modern-day Visonian State.

This picture depicts a Visonian woman and man performing a siamora dance in traditional clothes. It is perhaps the most popular form of dancing among Visonians and had become one of Visonia's national symbols. The word "siamora" came from Pan-Galeanic root word *s₂amo meaning "to wave," usually in the context of bodies of water, i.e. river or sea. Like any other Galeanic dances, it has been theorized that siamora originated as a war dance during the era of ancient 24 Visonian tribes. During the early medieval period, the dance became a part of harvest (in the hinterlands) or fishing celebrations (in the coastal areas). Siamora is played by 8 men and 8 women, all carrying roċeva (tubular drums and sticks) for rhythmic purposes, dancing in a circle, and making motions that are amplified by the ribbons on their drumsticks.

However, the emergence of Caulist fundamentalism in 1964–1967 amid the Third Viso-Samgurtian War spelled doom for this very tradition. When the theocratic dictatorship seized power in 1967, they attempted to cleanse the Visonian nation of anything not in line with their "purest interpretation" of the "purest scripture." This period is called the "Caulist Revolution." Siamora was perceived as a "deviant" culture for these reasons: first, it is a mixed-gender event. Second, the fundamentalists think women are not supposed to be outside without a guardian or someone related to them. Third, listening and making music, as well as using instruments and singing, are considered as a "grave sin" for it is a "wicked distraction against piety." When the revolutionary violence reached its peak in 1970, siamora has been considered extinct in its own homeland.

Due to the isolationist nature of Visonia's clerical dictatorship, it is difficult to determine how far does plenty of Visonian cultural elements survived the Caulist Revolution. Some refugees coming from non-urban Visonia attested that mixed-gender siamora, which is its original form, persisted on a small scale in areas far from major cities as late as 1980. Luckily, this form of art has been preserved by the Visonian diaspora, where it continues to be a staple part of Visonian cultural expos abroad.
