Infinity Core

The Infinity Core is a piece of highly sophisticated technology created by the Tsrif'Reldu. It was later discovered by the Ethereans and integrated into their tech.

Purpose/Function
The sole purpose of the Infinity Cores is to generate an infinite quantity of clean energy. Thus, it has become an integral part of the Ethereans' tech, especially their starships.

A device called the Infinity Booster was also created by the Tsrif'Reldu to work in tandem with the Infinity Core.

Infinity Booster
The Infinity Booster is a device that essentially latches on to Etherion currents, allowing the host ship to ride these currents through space at blinding speeds.

Creation
Infinity Cores can be created by hypercompressing active Etherflux Tesseracts. They become hard and crystalline, but retain their energy-generating properties.
