Few vessels survive the insidious whirlpools and ravenous sea monsters of Azlant to reach the open waters of the western Arcadian Ocean and the lush continent for which it is named: Arcadia, a wooded paradise 4,000 miles west of Avistan. The handful of explorers to venture there and return to the courts of the Inner Sea speak of vast natural resources, gorgeous panoramic displays of unbridled nature, and fierce native inhabitants. Ulfen longships sworn to the Linnorm Kings first discovered Arcadia 5,000 years ago establishing a community called Valenhall on the rocky northwest shores. At first, the new land seemed unclaimed by civilized races — a place of limitless natural bounty with few protectors save the occasional monster or ferocious animal. In time, however, the solemn natives of Arcadia made themselves known, savaging the Ulfen settlement in hails of arrows and hurled tomahawks. A great shieldwall and rampant disease accidentally imported from Avistan thinned the ranks of the hostile natives, whom the Vikings called skraelings, creating an uneasy balance of power between Avistani settlers and native Arcadians that exists to this day.
Since ancient times, Valenhall has served as the resting place of Linnorm King monarchs, the final destination on their last great voyage upon the seas of Golarion. Survivors of an arduous, almost impossible journey from island to island along the northernmost seaways of the Arcadian Ocean, settlers of Valenhall and their descendants believe themselves to have traversed spiritual pathways into another world, a true afterlife fit only for the most valorous warriors. Guarded by einherar and valkyries and ministered to by a trio of reclusive norns, Valenhall certainly seems to have one boot firmly planted in the supernatural world, leaving it relatively free from interference from the skraelings or other Avistani settlements, such as Andoran’s lumber and agricultural colony at Elesomare and Cheliax’s voracious gold mine and slave operation at Canorus and Anchor’s End.
