The Isles of the Seven Deaths

Far far to the north, in the midst of the Frozen Sea, lies a chain of seven islands.  Rarely are these islands reachable due to the icy seas surrounding them, the strange currents when the water is thawed, and the dangerous mist that always seems to cover them.  No one still alive or old enough to remember has ever dared to travel here, no longer are there even stories of travelers to these islands - no one dares to speak of them anymore.
