Sviar

The Sviar are one of the great nations of the North. Their last kind, Ingjaldur the Mad, killed himself long ago, and since that time the Raven Throne of Svialand has been vacant. The Sviar have no king, but are ruled by the jarls they elect from among their own tribes. The jarls are advised by the godhar and gydhjur (vide Godhi/Gydhja) (priests and priestesses of the Northern faith), for the center of their religion is the Great Temple at Uppsalir.
