Abandoned Industrial Junk Star
It was originally a bustling planet
Rich in a rare metal
After 100 years of vigorous development
Rare metal has been excavated done
Mining companies leave one after another
then
Some processing plants have also closed down
More unemployed
People who opened small shops closed
At last
Most people left
Those who did not leave are dead
This became the planet that the Federation uses to discard trash

废弃的工业垃圾星
这里本来是一座繁华的星球
盛产着一种稀有的金属
经过100年的大力开发
稀有的金属被挖掘完了
采矿公司陆续的离开
接着
一些加工厂也倒闭了
失业的人变多了
民间开小店的也倒闭了
最后
大多数的人都离开了
没离开的也都死了
这里成为了联邦用来丢弃垃圾的星球
