When an agent from the Imperium Intelligence Service shows up on Tiadaria's doorstep, he leaves her with unwelcome news. Recovering from their brutal defeat at Dragonfell, the Xarundi are seeking out an ancient and incredibly powerful relic buried in the snow and ice of the Frozen Frontier. Tiadaria travels to the city of Ethergate to seek out an apprentice skilled in magical research. Even with his reluctant help, unearthing information on the relic proves to be almost impossible until a savage turn of events puts them on the right path.

Now it's a race against time through some of the most unforgiving territory on Solendrea to beat the Xarundi to the relic and stop them from unleashing its devastating power on the unsuspecting masses.
