Flight of the Dying Sun: Eberron: Heirs of Ash, Book 2 (Unabridged‪)‬

Some say it was a super weapon, some a portal to other worlds. Whatever the truth, all know that the Legacy disappeared on the Day of Mourning. But now Ashrem's heirs have unearthed clues of the Legacy's whereabouts, and the hunt is on. Some want to use the Legacy to bring about a new age. Others want to destroy it before it shatters the fragile peace in a world that is trying to put war behind it. But others find their fate caught in Ashrem's Legacy, and in the frozen lands of the far north, they'll have to find a way to stay alive before they can save the world.
