Asterhaf
Asterhaf (lit; The eastern sea) is a large ocean region to the east of Scandera and north west of Asterland, it is also known by the names Nardsja, svarthaf, Kakto Dour, Ishashi'mo (literally, the norhtern sea, the black ocean, the norhtern ocean, or the Sahsi/Scanderan sea) and it is very much considered federal waters by the federation but it does not enforce as an extreme claim to the open ocean as it does to the entirety of Vattnafalten as they do in the south and they don't enforce it as their entire EEZ. The ocean is located aroun Scandera, especially Imeriata proper, Vedian, and the northern ice plains to the east, surrounding Asterland, and Salywa centrally and in the south can one find the island of the dragon grave, Taranaka, and Salmo to the south and to the far north can one find the Cairn shore.
The sea is noted for being very deep in it's centre with tectonic plates slowly driving Asterland away from Scandera resulting in a very deep sea and is the home of the leviathan whales that the sea is known for and submerged volcanos are common and has resulted in several small island chains dotting the region home to mostly Scanderans, Scanderiansied natives, Giels, or even smaller ethnic groups that are just commonly lumped in as mere "Havsavalk" by federal authorities however these peoples are quite rare in modern times as Scanderianisation have historically either assimilated such groups or replaced them with scanderan settlers over several centuries.
Economically and military is the region very important and serve as a large transport hub between Asterland, and Salywa and Scandera itself but it remains far from as well used as the Vattnafalten. Historically have the ocean been very important for the people living around the sea and trade between Asterland and Scandera have always travelled from the north to the Scanderan Northern iceplains before they turned south around Aserstrand. Even today is fishing and whaling very important industries for the region but oil drilling have recently also sprung up as an economic activity in the region. Militarily does it provide the Federal and royal fleet with massive naval bases dotted around it to ensure federal control over the region and ability to strike south to defend Vattnafalten without any danger from powers of federal technological levels.
Geography
The geography of the region is due to two factors, the divergent continental drift from the south Scanderan and Asterland continental shelves that have given birth to the very deep ocean between Scandera and Austland but also the warm Vattnafalt stream that brings warm ocean water from the south and brings down cold ocean water to the eastern Vattnafalten. This is responsible for the heavy rainfall on the eastern Scanderan coast and the temperate and artic rainforests that one can find there. From the Islands can one also find large meltwater runoffs that provides the sea with minerals and causes yearly algae blooms that contributes to large fish gathering on the coast to feast and in turn invigorates the ecosystem.
This has divided the sea into five distinct regions, the northern kelp forests, the dense pine mangroves of eastern Scandera, the shallows of Asterland, the volcanic islands, and finally the deep black sea. Each of these regions are however connected through the sea and affects the wildlife that often migrate between them in large titanic schools.

Islands
Most of the islands found between Scandera and Asterland is volcanic in nature, they tend to be very small and rising out as large pillars from the sea making these areas are often very fertile with large birch forests cover the fertile volcanic soil. Similarly do they cause large meltwater to pour into the sea every spring and summer that causes large algae bloom and massive population blooms of huge schools of fish that feasts on these algae which in turn causes annual migration of predatory fish and mammals from the coast out into the deep waters to feast either on the fish, the algae, or the migrants.
Deep Sea
The region most thought of when most federal talk about the Asterhaf is it the deep sea they think of and its deep sea, this is a very deep region due to the continental divergence occurring between Scandera and Asterland and as a result is it the home of large very deep trenches, volcanic activity is high and one can find numerous volcanic island chains dotting the deep sea as large pillars. This is also the home of the largest of the animals of the sea and one can find massive filterfeedeing whales and sharks that travels the deep ocean but also massive macro predatory whales, large kraken squids, and sea dragons that hunts these giants. This has historically also traditionally kept sea exploration on the deep sea somewhat limited and very dangerous and instead forced sea crossings to go north before heading south. However modern ships are generally safe from attacks from these giants even if danger is still present if one would underestimate them.
