The planet Veranis (an Anglicization of a native term) is the fifth planet of a spectral class F star called Dyaxor A. It was terraformed into an Earth-comparable environment by the Familiar Eldren during the Carboniferous Period, and has been periodically stocked with new species since then. Veranis is one of the more Earth-like of these terraformed planets, its mass, diameter, rotation, axial tilt, and other physical parameters were naturally very close to that of Earth before the Eldren even began their work.

In the relatively recent geological past (about 40,000 Terran years ago), Veranis was in the grip of a planetary glacial period. Though the planet has open ocean at both poles, ice floated at the poles and glaciers spread through the land areas in the higher latitudes. In 2123, though, that period is long past, and now the planet has transitioned into a hothouse period. The axial tilt is sufficient to produce significant seasons, but most of the land areas of the planet never experience extreme cold, except at the highest mountain elevations. By Terrestrial standards, the seasons range from 'mildly warm' to 'unbearably hot'. The slightly higher rotation rate (compared to Earth) and the steady flood of energy from the class F star combine to give Veranis lively weather and regular powerful cyclonic storms in the tropics.

The Familiar Eldren established a population of the H. lakegrandis species there around 73000 B.C., and that race in turn brought in a population of H. vertara from the neighboring world, and this race dominated the planet after the lakegrandians vanished. In the late Twentieth Century an extrastellar race of humans, the Thakarians, conquered both the terraformed worlds of the star system, and they were ousted in turn in 2105 by humans from Earth.

The ancient lakegrandian population of Veranis became quite technologically advanced by 31,000 B.C. They had achieved interplanetary flight, and archaeologists in 2123 debate whether they had achieved translight interstellar travel at the time of their Disappearance. Their technology appears to have been sufficient for the purpose, and they definitely had access to orichalcum, but whether they had actually done it at the time of their Disappearance remains unclear to Terrestrial archaeologists in 2123.

Certainly they had achieved many other things. Their ancient cities covered hundreds of square kilometers in their day, and they sculpted entire mountains to their purposes. Major rivers were rerouted, and they drilled deep-mantle taps as well. They brought in a breeding population of the Homo vertara who lived on their neighboring planet. Why they did this remains unknown, they apparently made no effort to raise the technological or cultural level of the vertarans that they settled on their world, and they appear to have gained no known benefit by this transplantation.

What is known is that some time around the year 31,000 B.C., Gregorian, the entire billion+ population of lakegrandians living on Veranis vanished. Their fate remains totally unknown in 2123. The archaeological record shows little indication of what might have befallen them. The archaeological record seems to indicate that they were still thriving, still advancing, at the time of the Disappearance. There is no indication of warfare, no skeletons scattered among the ancient ruined cities. The cities and other ruins suffered damage from the elements and time after the Disappearance, but show no sign of damage at that particular time.

Exactly how fast it all happened is also unclear, though archaeologists have narrowed it down to a period of about a Terran century. It might have happened faster, it was fairly certainly no longer than that when what Happened, happened.

With the ancient lakegrandians gone, Veranis was inherited by the vertarans that the lakegrandians had brought to their world from the neighboring world.
