Arria (planet)

Arria is an undocumented planet located in the Andromeda Galaxy, and is occupied by the descendants of the first wave of Alyssian refugees fleeing the destruction of the star. The planet is a Terra class planet, with a oxygen rich atmosphere and a number of biomes similar to those of Earth.

Over the thousands of years that they'd established themselves on the planet, the Alyssian population has since exploded, growing to just over 800 million across the planet. This count also includes members of the Empire who had to ground their ships due to a severe stellar radiation from the supernova of Alyssia. The Empire maintains several megacities concentrated in the western section of the planet, which are under Alyssian Empire rule. These cities extend their authority outwards across a significant portion of the planet, including over the outer territories living on the outskirts of the Great Wall, which encircles the immediate area of the megacities and protects against the rising population of Alkurri on the planet.

History
The Alkurri originally had complete control over the planet. A mild sensitivity to sunlight prevents the Alkurri from establishing pack nests in the open areas of the planet, so initial readings of the planet typically hide their presence. Over thousands of years prior to the discovery of the planet by the Intergalactic Exploration Commission, several starships fleeing the destruction of the star Alyssia either crashed or were forced to land due to damage sustained from the supernova. The planet itself was minorly affected. However, over a dozen starships already in poor condition ended up planetside. The remainder of the armadas, both of the refugees and the Empire's remnants, wrote the vessels off as a loss and continued on their flightpath out of the galaxy.

The refugee colonies are growing at a moderate pace, as many of their residents have banded together to build up smaller cities. Despite the growing threat from the Alkurri, the colonies themselves have built functional matter manipulation systems, as well as a construction drone framework, allowing them to build residences for their citizens, as well as providing sufficient food and water. The colonies are under the control of the Empire, who resides in megacities where Alyssian Law is strictly enforced. The colonies are currrently fighting for their independance, and the Empire has been stayed off due to the colonies possessing weapons technology salvaged from the starships.
