The Godless Matron is home to many, resembling a micro-society for those who wish to live outside the typical 'rule' of the galaxy. The Lucrehulk-class battleship's massive hangars have been converted into dwellings as a result. Chute Town is the most notable of these makeshift towns. Many shops and storefronts have been constructed to take advantage of the higher volume of foot traffic. In addition, many ships and crews arrive into Chute Town to sell their "well-earned" commodities, weapons, or artifacts. It is commonplace to find the best and the worst gear the galaxy has to offer, it is only a matter of how big your pocket book is. The 'streets' are patrolled regularly by the crew of the Matron itself, leaving would-be miscreants to be more wary, lest they find themselves on the receiving end of a pirate's sense of justice.
It is built mostly out of spare durasteel panels from derelict ships, dismantled machinery, or any other source or material the pirates could scavenge. It spans the length of the massive portside hangar of the Matron, reaching from it's heavily protected reactor — hidden behind triple-reinforced blast doors and a guard retinue — all the way to the hangar entrance where the many incoming ships unload their cargo. It is more than a mile long, over five hundred feet wide and up to three stories tall, covering most of the floor. Chute Town's streets are a miniature maze, weaving in between buildings on several levels. Verticality is key for the masses of shops and bars to operate without interfering with one another. The main street is nicknamed Murder alley, mostly because all the weapon shops are prominently opened there.
Illumination banks are staggered along the walkways and buildings to provide enough light for the society to function. Still, the 'streets' are left dim with a low hanging fog built up from the collective humidity of so many people in one space. For those calling it their home, there is no such thing as 'off hours'. A large crowd bustles along at all hours, an exotic assortment of individuals from countless planets and the warring gangs that divvy up the territory within. It's the perfect place for those looking to disappear in the crowd.
Syntax
The comma after saber should be a semicolon.
There should be a comma after belongings.
You need a comma after illumination.
Story
I like the way you started this post right in the middle of some action. It was a good hook to grab the reader's attention and set up Riku's motivation in this particular encounter. You introduced your opponent and set them up as a rival for the same prize. Overall, a solid opening post and excellent use of the 750 words you were allotted. I know the word cap can be a challenge at times and you rose to the occasion in this post.
My main story quibble is that the identification piece seemed forced.
Why would Kooki give her name and Clan affiliation out so flippantly? I didn't count it as a realism detractor because it didn't contradict her character sheet per se but you should make note that Kooki has +4 Subterfuge and +3 Manipulation. Where this did hurt you is in story, albeit in a very minor way. It was a "meh" moment in an otherwise solid post.
