The South Sea Islands
Time is not measured in traditional ways, but their tech is neolithic
For thousands of years, the islanders of the Southern Sea have prospered in relative isolation, developing a vibrant shared culture of navigators, traders, storytellers, hunters, weavers, and healers. They worship the sea as a mother goddess, and shaman-like 'listeners' and 'speakers' play a significant role in society by coordinating the worship and embodying the power of the ocean. The islands are dominated by the wealthier, semi-agricultural peoples of the coastal plains, who maintain robust inter-island connections across which trade goods and stories are constantly swapped.
There also exist smaller populations of semi-nomadic mountain people, who are somewhat cut off from the broader culture, with unique lifestyles and religious practices. In recent centuries, the islanders have had their lives disrupted by violence — first there were the raids from the neighboring Teklatesh Flower Xings; then the internal Clan Wars for political dominance; and now the colonialist invaders of Fareau, an industrial civilization from far across the sea.
