From Destinypedia, the Destiny wiki
Riis was described as a finely crafted paradise, possibly so after the coming of the Traveler whom the Eliksni revered as "The Great Machine", 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, and at times appeared green as well. Well-regulated air traffic was common.
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 homeworld and civilization would be destroyed by an unforeseen event known as the Whirlwind when the Darkness invaded. At some point Oryx also 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 century long journey into space to locate the Traveler in hopes of returning to their former glory.
Following the arrival of the Pyramids to the Solar System, Eramis, Kell of Darkness led the Eliksni House of Salvation in constructing a colony on Europa known as Riis-Reborn, in the memory of their homeworld.
