Book 5 in the World of Melarandra series.The Realm of Lungast trembled as word spread: The Therin have arrived. With a cloud of dust which could be viewed for miles, they thundered into the realm. Their goal was no less than to destroy their ancient enemy and enslave all who opposed this.But there is still hope.Within the Fallen Giant Mountain lies the Horde of Karabine. A horde which spans the ages and holds as many dangers as it does treasures. Here Prince Eric, War Wizard and next in line to be king of the Free-Realm, travels to find a stone. The stone, along with a branch from a rare white oak tree, could be used to create the Staff of Mordenren. With this magic, Eric might be able to push back the advancing army. However, travelling across an unknown land is not without its dangers. Captured by centaurs, their quest to create the staff could already be over.Three armies join forces to fight this new foe and attempt a plan of their own. Once again, pages in a book lead a few down a different path in hopes of defeating this enemy. With Glomain and two dwarves attempting to access a strange magic, and Eric off finding what he needs to create the Staff of Mordenren, all the soldiers can do is hope they can hold off the Therin long enough for one to succeed.
