Marapur

The island lies in a part of the ocean dominated by warm currents causing a tropically warm and rather humid climate. Once a large island, Marapur has been very slowly but steadily flooded by the surrounding ocean for several centuries. This has caused the island to fray at the edges, where you can nowadays spot smaller islands and archipelagos in the water.
However, since the sea level rise is so extremely slow, the island's inhabitants, the Nagas, are not forced to flee or to do something about it. Rather, the so-called coastal Nagas adapted to living with the water and integrated it into their culture and way of life. Another group of Nagas that lives in the isle's mountain region is not affected by the flood at all.
Except for the mountain region, the island is mostly covered by jungle and lush grass. The Nagas have cultivated a plant which serves them as food but also as crafting material. The so-called Starleaf is grown on large farms. Also, the indigenous water lilies are of great use for the Nagas. The smaller ones form waterways between buildings and islands. Their giant relatives are sturdy and thick enough to hold fishing shelters and small shrines.
