Analysis of Setting- Section 2 (amarachi)

The story begins in 1866 and 1868 (The journey on the Nautilus beings during the summer of 1867). The story is set on the Nautilus, the submarine vessel designed by Captain Nemo. The Nautilus traverses Pacific, Indian, Atlantic, Artic, and Antarctic Oceans, and the Mediterranean and Red Sea.
Quote from the beginning of the novel, also explains a bit more about the setting:
"A thousand rumors were current among the population of the seacoasts and stirred the imagination of those millions who dwelt inland far from the shores of an ocean..../And everyone in Europe or America that had to do with navigation was deeply interested in the matter- whether sailors or merchants, captains or pilots, naval officers or rulers of empire."
Visually the novel is pretty dark and mysterious.
