Semeria

''"Entering Semeria's atmosphere there is no air that is breathable and so the native people to this planet have built enclosed cities within pyramids which allows them to breath." ''- The Great Library recording

Semeria is a desert planet within the Central Sector of the galaxy that is inhabited by humans that live in pyramid like cities that are enclosed due to the planet's atmosphere not being breathable.

Description
Upon entering the atmosphere of Semeria many people do not leave their ships until they enter the enclosed cities due to no breathable air on the planet's surface for people to breath in. On the planet's surface are many cities built like pyramids which house millions of people inside allowing them to live and thrive with air being produced for them inside these structures, alongside these cities each city was governed by a scientific branch that all built up to a science organisation called Alp Industries who are widely known for their inventions for military grade things and other things, the leader of the company with the title of the Administrator also runs the planet of Semeria.

History
Semeria started off in the Central Sector as a green planet covered with mountains, grass and forest areas however it would be during the Western Anarchy when Penta Wain and her army would manage to bridge into the borders of the Central Sector and with Semeria being the closest planet to the border began raining orbital bombardments down on the planet as Penta was informed that this planet was inhabited by the Central Army however the planet was only inhabited by the army by a very small amount and so this didn't really affect the army. With the amount of bombings done to the planet the once green terrain became a very white like desert that was left over from the ash of the bombs, this led to a 100 years passing before the planet became habitable once again with Alp Industries originally setting up in the year of 107 AO their own laboratories to harness the non breathable air that surrounded the planet's atmosphere. Around 10 years later in 117 AO the company would build enclosed pyramid cities for people from other planets to come and live on, the cities themselves also became experiments for the company to see if they could provide breathable air within these closed off cities for people to live and thrive in.

In the year of 124 AO the planet's experiment would be a success and the cities would open up to more people to live in which allowed the planet to become very populated, Alp Industries would continue to live on this planet to conduct their experiments and inventions on new things to bring to the rest of the galaxy including the Central Army with things like weapons.
