Yarrossi

The Yarrossi are a species of sentient creatures native to the planet Yarross. The Yarrossi are a very advanced and aggressive species. They are most well known for their role in the Great Yarrossi Enlightenment, a series of conquests across the Freyja System which caused unrest and revolution on many planets.

History
The Yarrossi arose from small forms of life on their planet and are the only large species on their planet. As they grew they developed three distinct clans: The north, south and mid Yarrossi. As time went on the Mid Yarrossi were integrated into north and south, and eventually the southern, more aggressive Yarrossi defeated and exterminated the northern Yarrossi. The Yarrossi developed spacecraft very quickly and used the abundant minerals on their planet to create massive hive ships, as well as smaller one-manned space craft, known as Yarrossi Vipers. With their new armada they began to explore the galaxy, conquering several nearby planets and enslaving, then exterminating the native species. When they encountered the planet Untra, the native Untralans fought back, along with help from their allies, who eventually formed the Union of Free Planets (AKA the Union). This marked the beginning of the Great Yarrossi Enlightenment. After many decades the war like Yarrossi were driven back to their home planet, where they began to take a new, less aggressive approach.

Today, the Yarrossi are still not allowed to leave their planet due to the atrocities they committed during the Great Yarrossi Enlightenment, however public opinion on their exile is beginning to shift to forgiveness. While some Yarrossi accept that their punishment is just and they will must make do with what they have, others are angered by the fact that they are being punished for the crimes of their ancestors, and that the planet they have been left with has very little opportunity.

Physiology
The Yarrossi are a slug-like group of life forms, mainly grey but with a thick yellow stripe down their back and black lines beside that. They have two eye stalks which protrude to the sides of their head, and they have four long arms with "hands" that can mold around objects to control them. The Yarossi are slow creatures, gently sliding along the ground while leaving no trail behind them. While on Yarross they absorb most of their nutrients from the ground beneath them, however they can also consume nutrients through their "hands". Giant Ground Amoebae are a very nutritious delicacy for Yarrossi.
