The extensive underwater mountain system, called the Seascape Mountains, existed in the aquatic realm of Dac. This area was situated to the south of the Algae Sward, nestled between the Domed City of Aquarius and the Valley of the Giant Oysters. The tallest points of the Seascape Mountains extended above the Dacian seas, creating a string of islands called the Hakawa Islands. This area served as the habitat for a type of marine mammal known as Whaladons. A Human Whaladon hunter, Captain Dunwell, often hunted in these waters, accompanied by a small team of Aqualish fishermen. Whaladon flesh commanded a very large sum on the Imperial market, making it highly valuable to individuals in Dunwell's line of work. He relentlessly hunted and captured the native Whaladons, nearly driving them to extinction. The Whaladon Processing Center was centrally located within the Seascape Mountain range. An aged Whaladon, widely known as Leviathor, guarded the Seascape Mountain area, endeavoring to protect his Whaladon kin from exploiters such as Dunwell.
