With her husband Erik and the young witch Wren, Freya explores cities full of ghosts and finds survivors on the edge of madness. She finally reaches the ancient viking city of Rekavik, where she meets the deadly witch queen Skadi and the vicious warrior Leif Blackmane, but the only person who can cure the demon plague is the person who created it in the first place, a stranger who carried a sword full of captured souls, a man who was murdered five years ago.
So Freya travels deep into the wilderness to find a dead man, to save a lost king, and to wage war on an army of bloodthirsty monsters, even as the people she loves most fall prey to the plague, one by one in this dark fantasy adventure.
Welcome to the world of AETHERIUM, where wondrous machines sail the seas and the skies, enormous beasts roam the earth, and the restless dead whisper to the living. Similar to our own world in the sixteenth century, AETHERIUM explores a reality in which many of the megafauna did not die out, including terror birds and saber-toothed cats, and where a devastating Ice Age continues to ravage Europe while African queens rule over the most advanced nations in the world. But strangest of all may be the science of controlling the souls of the dead using a golden metal with many names: sunsteel, orichalcum, and... AETHERIUM!
