Magnetism in the Wumpa Archipelago

Magnetism in the Wumpa Archipelago is supercharged compared to other islands, due to subterranean power gems that contain powerful energies left over from the splitting of the Gondwana continent from Antarctica. The gems influence the islands, causing a magnetic sphere to surround the islands and reflect light. The magnetism also simultaneously strengthens the tidal waves around the islands, causing a swirling effect that directs ships around and away from the archipelago. Fauna and flora on the islands are affected by the magnetism, which causes fauna to pump more carbon dioxide into the air. As a result, fauna on the islands are typically larger and this can be seen with Nadrassil, Wumpa Island's large 'world tree'.

Civilizations on the islands have long sought to tap into the power gem's energies, and doing so allowed the Lemurian civilization to thrive through its golden period. Certain gems are more powerful than others, and the Earle'dein have kept a small cache of these gems in their possession. The Lemurians symbolized the magnetic energies in their art as a pit of evil serpents twisting and turning underneath the islands, and this likely played back to the race's Edomite heritage. When the Cortex Corporation made landfall on the archipelago, they sought to use the gems to power their evil devices. It is believed if harnessed correctly, the power gems could power destructive devices comparable to nuclear bombs. It was ultimately their reckless mining efforts that caused the magnetic sphere of the island to dissipiate enough to allow for discovery.
