Feldspar

Feldspar, once known as Eh'fyt, was a terrestrial planet in the Core region. It is the human base of operations in the Rak Thy'renak systems.

Pre-human contact
The Ke'fet discovered Feldspar when they first ventured out into space, naming it Eh'fyt. It was originally left uninhabited as the Ke'fet were more accustomed to warmer temperatures. Some inhabitants of Arke'hyt went there on a spacecraft as an attempt to start a colony, but it ultimately failed.

Human contact
When humans came across this system while exploring the unexplored regions of the Core in the year 42, they discovered Feldspar first, and made a small base there. By this time, any traces of the Ke'fet colony attempt were gone. They next discovered Arke'hyt and landed there. Realizing there was already a species here, they made a deal with the Ke'fet that they would live on Feldspar but not interfere with Ke'fet activities.

Post-human contact
By the year 60, humans and Ke'fet lived in peace, but the majority of Feldspar's population was still human.

The Zeptonova flew above Feldspar on its way to Arke'hyt.

Feldspar was one of the possible targets of the Reality Beam, due to its significance within the Ke'fet territories. It was added to the list of possible targets as it would violently change the outcome of the ongoing Arpalogarian War. However, it was not chosen.
