During their time on Spherus Magna, the Great Beings created seven Element Lords to lead the tribes of Glatorian and Agori. The Element Lords would soon discover Energized Protodermis leaking from the core of the planet, and began fighting over the substance, which led to the start of the Core War.

In an attempt to end the Core War, Heremus and Crasevous created the robotic Baterra to target and kill any armed combatants in the war. The Baterra were highly effective in combat, but they failed to end the conflict. The Baterra also constructed the Valley of the Maze around the Great Beings' central fortress of operations. Angonce later ordered Heremus to shut down the Baterra. Unbeknownst to him, however, Heremus left them active, claiming that they malfunctioned.

The Great Beings went on to create a new species of bio-mechanical beings inspired by the Glatorian and Agori called Matoran, whose purpose was to maintain the Great Spirit Mata Nui from within. After much debate, the Great Beings decided not to make the Matoran sapient, in order to prevent situations like the Core War from happening within Mata Nui. Heremus and Crasevous were both opposed to this decision for their own reasons.

When all preparations were completed, Mata Nui was readied for launch. However, the Core War caused a chain reaction within the planet's core that split Spherus Magna into three pieces, the forest moon of Bota Magna, the ocean moon of Aqua Magna, and the desert planet of Bara Magna. Some of the Baterra remained stranded on Bota Magna.

Disappointed by the actions of their civilization, the majority of the Great Beings left Spherus Magna. Rather than leave, Crasevous met with Heremus, and they devised a plan to make the population of the Matoran Universe sapient, so upon Mata Nui's return to Spherus Magna, the pair of Great Beings could rule the Spherus Magnans uncontested.

Crasevous entered the Matoran Universe to execute the plan while Heremus hid in the Black Spike Mountains, to await Crasevous'  and Mata Nui's return. Heremus was accompanied to his hiding place by his army of Baterra, who he ordered to stand guard over him.

Later, the Skrall would migrate north into the Black Spike Mountains, which triggered the Baterra to attack. They proceeded to ravage the warlike tribe until the Skrall were driven south. This wiped out all but one of the leader-class Skrall.

The Baterra would continue to occupy the Black Spike Mountains, slowly inching their way further and further south for many years.
