Jake's Dragon 6 - Deep Earth

Long before even dragons roamed the planet, the spores of the borlamites were biding their time in the heat and darkness of deep Earth. They were waiting for the surface to cool and the seeds of life to take hold and turn a barren rock into a pearl among planets in our galaxy. As they prepared to emerge from beneath Earth's tectonic plates and turn the bio-matter of the dead and dying, into food for the budding flora and fauna, their birth was interrupted by an asteroid strike. The planetary conditions suddenly changed, and the borlamites continued to sleep.

They slept through the darkness enshrouding Earth. They slept through one ice age after another while the planet underwent a multitude of changes. They slept for another 65 million years.

Eventually, the temperature began to increase, and with global warming came the long-awaited germination and birth of the borlamite spores. As they emerged, they expected to find a world of giant dinosaurs inhabiting the region from the Tropic of Cancer to the Tropic of Capricorn. Instead, they found a different creature had replaced them as Earth's dominant species: Mankind.

Whether dinosaurs or humans, the borlamites were hungry, and in the absence of unburied dead, they would create their own... and eat them.
