Still following the Mascodagama thread I discovered that the Russian various conquests during their Artic expeditions to find a link between Alaska and Siberia ( maritime exploits that also included Argentinian Patagonia in the "netherworld" of South America ) were ended ( like Mascodagama´s last act ) by the Crimea war.

After its defeat in the Crimean War, Russia did not want to cede its Alaskan territories to Great Britain and so transferred them to the United States in 1867. This marked the end of Russian presence in North America. Russian explorers contributed to making known the west coast and its people, from Alaska to California, including present-day British Columbia.

Remember Ada´s agonies in Patagonia, Captain Grant´s explorations of Cape Horn, Van´s dreaming of three fabulous trains and one that went through Brazilia to Viedma ( Argentine & witch).
The link is with Admiral Lisiansky ( he named the island where Demon´s plane crashed )
