Paradis Island

Paradi (パラディ) is an island on which the three Walls, Maria, Rose, and Sheena, are located. The island is massive in size and is just off the coast of Marley, the refined society where Grisha Yeager hails from.

History
Late into the history of the Eldian Empire, the 145th King of the Fritz family chose to abandon the conflict over the Nine Titans between the subservient Eldian families on the continental mainland and moved the capital of Eldia to Paradis, a remote island at the time. In the King's absence, the Great Titan War began. As Eldia lost more and more territory to the Marleyans, the minority bloodlines of the empire, the King gathered as many Eldians and members of the royal family as was possible before raising three Walls around their last piece of undisputed territory in the year 743. Some time after the raising of the Walls, the new Marley government built a 30-meter border Wall along the southern shore of the island to prevent the Titans from escaping to the ocean.

Geography and Climate
The island of Paradis appears to have a temperate climate, with the northern regions of the land being especially cold, rarely exceeding on the hottest summer days. However, the coldness of the northern regions of the island are alleviated by the occasional presence of hot springs. While it is unknown what area of Paradis is covered by the Walls raised by the First King, it is evident that the central region of the Walls is at a higher elevation than the outermost territories. Some regions of the land are home to Titan Forests, where the trees are known to reach as high as, possibly due to the unique content of the soil. The island of Paradis is also rich with various minerals and natural resources, which made the land a valuable target for the people of Marley over eighty years after the end of the Great Titan War.
