Northern Oceans
In the Northern Sea, most of O'koll lies, but the city of Thora also borders this sea of ice.
The Northern Sea is notorious for its many icebergs and extreme winds more so than the rest of the world Oceans. There are also countless underwater volcanoes though most of them lie dormant. This, however, means that both underwater mountains and unstable fissures are yet another threat navigators of the sea have to be careful with.
Central Sea
The Central Sea, which had many names in the past but after years of intercontinental travel and trade changed name to Central Sea, is not particularly shallow but is small enough to be considered a sea rather than an ocean. For such a tropical sea, it is surprisingly devoid of reefs of any kind. The wildlife is, however, bountiful, and a lot of fish types reside in the depths.
Yun'ka Ocean
The Yun'ka Ocean mainly borders Masuul and eastern Tondem but also encompasses the Navir Isles. It has a couple of reefs, some are but shallow waters while others are massive coral reefs and even sunken cities. Its temperature drops from almost icy in the north to tropical in the south and has the most diverse wildlife of the oceans.
Netinko Ocean
The Netinko Ocean is, unlike the Central Sea, very deep even for its small size. It ranges from the east of Belanna to the tip of eastern Tondem and is mainly cold or temperate.
Banobi Ocean
The Banobi Ocean covers the most latitudes, except for the Northern and Southern Oceans, as it spans from the Lommom Fjord to the western shores of Fui Ley. The weather fluctuates a lot and especially in the south is the temperature difference very stark with volcanic activity keeping some parts of the ocean warm year-round but also in the equidistance is it tough to predict. The middle of the ocean, and especially the Missing Dome, has a lot of unstable magic surrounding it which makes the weather equally unstable.
The Banobi Ocean has one big reef to the south of the Dome, but it is unknown if these two have anything to do with each other or their existence merely is parallel.
