Expanded the description of Serendipity

It is a unique space station. Designed to be run automatically, by built-in machines and a fleet of drones, much of the station's volume is machinery, with no space for humans to exist inside. Exceptions are Serenity's private quarters, attached to the main body of the station, a small commercial/residential wing, and the space port section of the station. Her private quarters are separated from the rest of the foot traffic areas by a security hallway, and is placed next to the bulk of station's processing and manufacturing. Attached to the security hallway, at an inconspicuous place, is the mixed commercial/residential wing. On the other side of that is the spaceport, where most of the foot traffic is kept. It is possible for merchant transports to forgo docking and receive bulk goods by drone.
   If you need something built, the station can probably build it for you, charging for materials and power consumed. There's a hydroponics farm, and even a small ranch for meat, though meat is sold to certain customers first based on a revolving schedule. The space port is large, if only because she made it spacious and left further construction to whoever wanted to move their shop in. Security drones patrol the space thoroughly, a promise kept for the protection money she collects. They're not dressed to be intimidating, but they're certainly identifiable. One can be seen occasionally in residential.
