“ | 532 Herculina is a large asteroid, approximately 260 by 220 by 215 km. It’s not spherical, but rather has a blocky shape. The asteroid has been given artificial spin, giving it a gravity of approximately .28 g. Two external ship ports are visible on the exterior of the asteroid. A small freighter is already docked at one of the ports. There are also several other smaller airlocks (for access to the asteroid’s surface) and external venting shafts at different locations around the asteroid. | „ |

Herculina (designation 532 Herculina) is a large asteroid, with a diameter of around 225 km. Originally a mining operation the asteroid remained in zero-G until later being spun up at great expense in order to experiments to be conducted.[1]
In the RPG

The Station is guarded by Vector Security, which maintains a nine person security force equipped with sidearms and light body armor.
Herculina Station has been totally repurposed and mostly rebuilt from its original mining use, all under the direction of NariDreik. The interior is mostly carved stone outfitted with molded plastic where needed. The rooms and hallways are quitespartan with no attention paid to décor.
Security Center
This is a small room where the Vector Security guards maintain a vigil over the entire station. The control panels here control the doors and cameras throughout the station. Fortunately for the characters, the guards are usually incredibly bored and spend most of their time surfing news and playing games on their personal terminals rather than paying attention to the cameras.
Living room Quarters
The living quarters are small and spartan. The scientists have almost no personal effects. Each room has one or two bunk beds. The guards share two rooms with two of the guards sharing bunks. Dreik has a room to herself. There is a central dining and recreation area, but it shows only the most cursory signs of being used.
Storage rooms
There are a couple of large storage rooms that are filled with empty crates, food, and spare and dis-used medical supplies. They aren’t checked by the guards with any regularity.
Power room
This room houses Herculina’s reactor and support equipment. The reactor provides all of the station’s power needs, and access to the power room is restricted to authorized personnel only.
The lab
The lab is the real heart of the nasty business being conducted on Herculina.
