Riis

Riis was the homeworld of the Eliksni, and once visited by the Traveler.

Overview
Riis was described as a finely crafted paradise, possibly so after the coming of the Traveler whom the Eliksni revered as a god, and the ether is said to have run freely. "Carefully tended lakes and rivers" are mentioned along with "fields of lush iridescent crops" and "groves of starkly colored trees". The sky was a light pink, likely due to ether enrichment. Well-regulated air traffic was common.

History
The Eliksni made during their Golden Age twice the advancement in space exploration than Humanity. Their ubiquitous cloaking technology was originally designed as toys for children. During this time, they came to control multiple star systems until an event known as the Edge Wars brought infighting among the Houses, and later ended by the House of Kings and House of Judgement to usher a new Golden Age.

Their home world and civilization would be destroyed by an unforeseen event known as the Whirlwind after Oryx struck the Eliksni civilization and slew Chelchis, Kell of Stone who made a final stand.

In the aftermath, the surviving Eliksni became embroiled in a bloody civil war over their civilization's ruins, before achieving a tenuous peace and abandoning what remained of Riis to embark on a journey into space to locate the Traveler in order to return to greatness.

Almost half a year after the Pyramids returned to the Solar System, the Eliksni House of Salvation, lead by Eramis, consctructed a colony on Europa known as Riis-Reborn, named in memory of the Fallen homeworld, opposite to the base of the Pyramid on the icy moon.
