Ancient technology of the Lost Ages, the Heart of Eden is a device thought to have once been used for terraforming worlds. In the Dawn Era, the age after the Lost Ages, a primordial named Storralk took this device to a world named Granitoid. Looking to change it to something other than a barren rocky wasteland, the Heart of Eden was powered up.
Terraforming on a world scale, with our best energy sources, changed the land around, nothing more. Our Nature Masters can do that. It wants more, a more complex and denser energy type, perhaps one conceived or no longer around ?
The Heart of Eden will join the others, sent to the vaults with the rest of the "beyond our current know-how".
- Storralk, from his book The Age Before - "Primitives Again"
In the God Era, for safe-keeping, the Heart of Eden was taken aboard the Crillion Comet where it remained until the age of the Lith-Crillion.
In 208 LE, on the world of Bal-Kriav, a great pyramid was built around the Heart of Eden. Like Storralk, the Lith-Crillion had the lofty goal of returning the Sands of Hell to the verdant valley it was before the death of Golruwyrm. Surrounded by an inhospitable desert, the Pyramid of Life and its engine, created bands of lush greenery outward for dozens of miles; yet nothing as grand as they had hoped.
In 446 LE, the device was tested near the Sea Breach. The test area, once a temperate forest, became a tropical jungle out of place in the environment around, yet still thrives.
