Grimnir is a primal world of islands spread across the winding Serpent Sea. The natives of Grimnir are the humans, elves, dwarves, and others that migrated here centuries ago when their original world was destroyed by the yoten—a race of spell wielding giants. Over the years numerous creatures of other races have been brought to this world and many have joined clans and become raiders of the Serpent Sea.

• Ever Growing Mountain. The inner mountain range, Turnfjall, still grows. It dominates the skyline from every corner of the world and from atop its peak the sky flashes with all the colors of the rainbow.

• A Primeval World. The Serpent Sea is ringed by lava and volcanoes and earthquakes are commonplace. Islands rise and sink often. Such extreme landscapes bring with them massive creatures including great bears, mammoths, and saber-toothed tigers. Even worse dwells in the forests of Turnfjall.

• The Long Winter. Winter has not fully withdrawn its cold grip the past two years and all raiders are apprehensive as spring approaches. Will winter finally relent? If not, many are going to die of starvation or in battle over scarce resources.
