Vihrie is an E-Class planet in the Rentxo Galaxy. It is home of 2 separate late Type-I civilizations, which inhabit the northern and southern hemispheres of the planet. It is located on the other side of the galaxy compared to the human outposts in Nova Rexina.
The planet is essentially split in half by a massive mountain range which runs across the equator, similar to an equatorial ridge. This may have been caused by a massive body reaching the Roche limit in the distant past. The body would be ripped apart by tidal forces and cause some debris to fall down on the equator.
The two civilizations are so far relatively isolated from the rest of the universe. They have made contact with several nearby, less-advanced alien species, but so far both civilizations have avoided conflict with foreign planets. Diplomatic relationships are rare, with even the Xcathli barely realizing the existence of the civilizations. So far both nations have rejected all offers (3, to be exact) of embassies on Vihrie. The nearest explorers from a major civilization are humans, which still have about 30 thousand light-years of distance to cover before reaching Vihrie.
These two civilizations seem to be in uneasy peace with each other, although not much is known about their past relationships. It is quite possible that a massive war had erupted between the two sometime in the past though.
