About Lord Kona; I don't suppose you've read anything in the Lore section of this site?
"Kona the Dread Lord had fashioned his empire on the premise that he was the supreme power of the world. Central to his power was the orb of dominion, a tool that he had conceived and helped wrought with the aid of his brothers."
...and so on. Kona, Dread Lords and Arnor are as much a part of the Elemental lore as the GalCiv lore
