Urum

Urum was without an atmosphere. Half of the planet was destroyed by a meteor which crashed onto the planet and ripped of half of the planet. The shattered part of the planet became the asteroid-field around this meteor. The planet's located in the urum system. Its inhabitants don't have to breath but because that wanted to trade with the other planets they built a huge shield with air inside it, this also protected them from the meteors. After the first Urunian war its population began to grow strong because of the many immigrants and a thousand years after the war the planet was one big city.

early history
After the discovery of space-traveling the Ununians built a giant shield with air inside to make trading easier a decade later all Urunians lived inside this shield. After the force war on Quary the Gray jedi built a Jedi Temple on the planet. and Urum became the center of the Urum Republic.

Early Urum Republic
In the early ages of the Republic many technological discoveries were made like the hyper-drive and the lightsaber, a lot of cures were found and the Jedi discovered a lot of new forcepowers. But it wasn't all good because a decease spread on Urum for witch they didn't have a cure, so many people died. Also one of the most powerful Jedi turned to the dark side and destroyed a large part of the city.

first ununian war
In 21 ABY Urum was invaded by the Empire but the Republic wasn't prepared for a massive war. With only a small group of fighters available they went into battle but soon knew they had no chance and they fled to Asto where they built a base and remained there for a year.

After a year they began their attack to free Urum. They captured the city but lost again it after two weeks fighting. In 28 ABY they tried again a small team was sent inside to destroy the shield generator while the rest fought outside the city. Once the shield was destroyed they send the men to retake the city. After they had retaken the entire planet they went to Conquer the rest of the system.
