The Akai Amulet
Kuro has eternally been a mystery to the dwellers of Sekai. After many years of trying to gain information about the culture and failing, Humans and Elves have generally given up on traveling there.
Dwarves are often seen in the capital cities of Sekai, and sometimes where there are rural villages surrounding the base of the mountains (although the land is barren and unforgiving). The general attitude of Kuro is one of “Don’t come here. Ever.”
