Pronounced "oo•FEH•lee•ohs", from the Nonic word for 'the world'.
Uphelios is the known world, including all settled nations that touch the Seven Seas: The Great Sea, The Black Sea, Dragon Sea, Marauder's Sea, Sea of Pearls, The Ring Sea, and the Sea of Fair Winds.
The Marauder's Sea is equivalent to our Mediterranean in climate and style, and the majority of Weaponry takes place here, especially around the Isla Theosopha in Rabinon, the largest of the Nonian Islands that divide the Marauder's Sea from the Sea of Pearls.
There is more land north and south of this map, but at the time of this tale, these lands are either unknown, or unimportant. As a point of reference for those wishing a direct comparison of size - the Isla Theosopha is approximately the size of the Japanese island of Honshu (the largest of the four).
