Two centuries prior to the events of Knack II, known as the time of The Crystal Wars, the advanced civilization of the Goblins, known then as the High-Goblins, feuded with humans and sought after energy-potent crystals, which were found only on human territory. Yurick, a High Goblin leader and master engineer, created the Ancient Weapons, an army of powerful robots, to eradicate the humans. The High Goblin empire expanded as they continued their onslaught, until the human leader and warrior Marius and his troops began to defeat the Ancient Weapons in a single with the use of rock, vines, traps, and cunning, propelling their continuous victories over the course of the war.

Once defeated, Yurick returned to his laboratory to create a control center to command his robot forces as well as more powerful weapons, most notably the Titans, for their final battle against Marius and the humans. While Marius and Yurick fought with their armies, Marius had sent a strike team while they were preoccupied, disabling the Ancient Weapon's control center and defeating the High Goblins.
