The Setting: An ark multi-generational spaceship traveling through deep space. The ship does not have windows. Lighting inside the spaceship is dim and sparse. You have the sense there may be a shortage of light bulbs, as a supply, like anything else in space, need to be carefully rationed.
The inside of the ship is very low rent. It looks more like a series of conjoined indoor gymnasiums than anything else. Plastic monkey bars, frayed rope climb to ceiling, tattered gym mats, faded red rubber dodgeballs, etc.
One of the gymnasiums has a very large tree growing up from the wooden floor, with vines roping down. The tree room is there for oxygen production.
