Dragons of Etchinstone: Northvale

From BoardGameGeek:

Finally, and at great cost, the dragons lay defeated. But now, a greater threat looms. Ancient evils have claimed Northvale, the warrior civilization in Northern Valorfall. These winter-hardened tribes would not have stood for loss without a fight. Surely this aggression must have been committed by only the most powerful adversaries. Some say they are the fathers of dragons. Others, dormant titans awakened from deep beneath the earth. It will require the greatest of Valorfall's Ether Mages to answer this challenge. Etchinstone calls for every elemental guild's best Mage to travel northward--to glory or defeat. Northvale is an 18-card expansion for Dragons of Etchinstone. The player takes the role of one of four powerful Ether Mages, one from each guild. There are four major guilds in Valorfall (red, blue, gray and yellow), each with their own school of thought on how best to wield the elements. You get the chance to pit your chosen Mage against a new landscape, progressing from the brutal dangers of the Severed Seaboard to the open--but deadly--horizons of the Whispering Fields. Then, navigate the dark terrain and evil secrets of the Forgotten Foothills. And, finally, traverse the icy mountain terrain and unmatched power of the Elementals in the unforgiving Northern region of Northvale. Then, if you are brave enough, face one of four terrifying new bosses. -description from designer
