Little is known about the purpose of the Arrow. According to the blast door map, It was a manufacturing center, Yet no machinery was found inside, and it seems to of been used for storage. It was discovered by the Tailies on day 27. It was rundown and abandoned. The only things inside the station were a few boxes. Inside one of the boxes was a glass eye, which probably belongs to Mikhail, a Bible with a piece of the Swan orientation video, and a radio which Bernard used to get in contact with Boone.

Horace Goodspeed worked at he Arrow station. On his uniform he is listed as a Mathematician.
Questions:

• What is the true purpose of the Arrow?
• Why was it abandoned?
• Does Mikhail have a connection with the Arrow?

Is what we have seen so far just a ground level entrance/exit like what the Swan has?
