The clouds of war gather over the West. Already the forces of the new Eastern Union have moved on the Far South. Now raiding parties sweep across the mountains as the Cairaga, under their ambitious young king, blockade the Kingdom of Ralgar. With time and manpower running short, newly promoted Lieutenant Fordain Abendroth must lead his companions on their first expedition to the mainland alone to find out whether Ralgar is to be invaded, and whether the time has come for the Golden Order to once again sally forth to defend its allies from the rising tide of darkness.

When his tribe’s village is destroyed and his brother taken prisoner during a raid by rebel soldiers, young Fordain Abendroth sets off on a quest that will change his life forever. He must journey to the legendary Kingdom of Aralia to seek help in rescuing his captive brother and restoring peace to his war-torn homeland. Along the way he encounters many friends, many dangers, and the truth about what it means to be a knight of the Golden Tree.

Ten years have passed since the Saltrak War. The dinosaurs of Cardolin once again enjoy a prosperous peace under the wise King Henrik. But the peaceful times are over! When a mysterious stranger arrives injured on the night of a fearsome blizzard, the kingdom's fortunes take a turn for the worse. Rumours abound that the stranger is somehow responsible for the ill turn in the weather. And when his old nemesis on whom he has sworn vengeance turns up to steal both the crown and the heirs of Cardolin, tensions rise to the surface. It is once more up to Astron and his friends to save the day. Battling bandits, disease, and the whims of nature alike, the brave Saurahallers must pull together to ensure their kingdom’s future and right past wrongs…or else watch everything they have worked so hard to build crumble before their very eyes.

Summer has arrived—and so has Edward the Slayer! After decades of relative peace, the dinosaurs of Cardolin are thrust into war when their barbarous neighbours invade without warning. With most of its veterans captured or killed right away, it's up to new arrival Astron and his cohorts to lead the defence of the capital city, Saurahall. But even it cannot possibly withstand the might of the battle-hardened invaders long without help. Thus, Astron must venture far beyond the city walls to seek out someone who can save the new home and friends he loves before it's too late.
