The Halls of the Ark

The Ark is a vast research space station. A gigantic satellite rotating around the earth. All rooms have gravity and some of the hallways even stretch to outside the ark where one can see the vast reaches of space, of course these areas are provided with oxygen and gravity. Much of the ark is rundown and damaged so most rooms won't get light and possibly even gravity. These hallways are attached to a variety of rooms, most of which was once used for research. The Ark has been out of commission for over 50 years.
