The Drow have gone too far this time.

Join Aurora, Tiamat, and her mates on the journey of a lifetime. They are hunting for the Drow that killed King Austin and stole his head. The journey into the Underdark, as the dragons call it, is not without its own perils. Realizing they are in over their head, Tiamat summons her once rival to aid them in their cause. Death and War ride through the hellscape with Tiamat, bringing the fight to the Drow.

What they don't know is there is a second attack happening at the same time on the surface. Alaric and Nicodeamus lead the charge to defend the surface from the Drow invasion. Can Tiamat kill the Drow King before it's too late?
