10 years ago, a cataclysm of unknown origin decimated the port city-state of Shore. Few survivors managed to escape north to Mistveil or the main continent who can speak of what they've seen. Since then, the world has grown dark, the flow of natural magics disrupted.
The seas have quickly been made impassable by a thick mist surrounding the islands, making navigation by stars or by compass impossible. Lightning storms rage constantly over the southwest, concentrated over Shore. Sea serpents were always a threat in the Southern Seas, but these days they've been washing up in the deltas of Miregrove and the beaches of the Twin Lakes dead or dying, missing huge chunks of their iron-scaled bodies.
The dead are rising, marching to the whims of something twisted and powerful, and rumours of the rise of the Cult of the Dark Sun are spreading everywhere.
