Physical geography
Location
The Oan Isles consists of the Home Islands and the Kohatu Isles. The Kohatu Isles are surrounded by the Caven Sea to the north and the Morstaybishlian Sea to the south. They are bordered by Peregrinia to the north, East Gemica (a Peregrinia territory) to the east, and Justelvard (a constituent country of Great Morstaybishlia). The Home Islands are surrounded by the Polynesian Sea to the west, the Pacific Ocean to the east and the Morstaybishlian Sea to the south and southwest. The Home Islands lie between 140°E and 158°E, and from the Aequator to 16°S. The Kohatu Isles lie between 109°E and 117°E, and from 7°S to 9°S. Geologists have long debated the continental shelf on which the Home Islands and Kohatu Isles. Although the Kohatu Isles and Home Isles share cultural, political, historic, religious and economic links with Aurora, they are technically part of Yasteria Major. They lie incredibly close to the tectonic boundary between the Aurora and Yasteria Major tectonic shelfs. Geologists believe that these islands will shift to the Auroran continental shelf entirely in several million years.
Topography
The Home Islands and the Kohatu Isles have similar topography. All of these islands were formed by the movement of the Yasteria Major and Aurora continental shelves against each other for hundreds of millions of years. The magma escaping from the crust through the tectonic boundary formed the islands over millions of years. The islands are usually mountainous with their core area comprising a mountain range with flat land on the coasts. The islands have many deep natural harbors that have allowed their use as ports for large ships. On the Home Islands, the oldest Islands are in the north. Due to gradual erosion over millions of years, they became smaller and their soil escaped to the sea, leaving many of them as rocky outcrops. Because the flat areas of the islands are at the coasts, the people lived on the coastal areas and were always close to the sea developing their culture and civilization around maritime travel and trade. Due to the abundant rain and fertile volcanic soil, the country is highly forested, leaving little room for human habitation. Thus, densely populated coastal cities emerged and land reclamation from the sea has been used to ease the pressure for land. Furthermore, agricultural land is very small and makes up a tiny portion of the country's surface area. There are many rivers and streams which come from the mountains but none of them are deep enough to carry ships. Moreover, very few natural bodies of water such as lakes exist. Humans have extracted water directly from rivers, and aquafirs.
