We live on a planet. We know it is a planet because we have heard of space travel but know of no-one who has ever done it and have no idea how it could be done. We have several examples of futuristic equipment but we live an agrarian lifestyle in a community of farmers in a fertile crescent of land bordered on one side by a sea and on the other by a desolate region known as the ‘Cursed Lands’. One day, while ploughing a field, a neighbour farmer uncovered a metallic hatch. He and his farm hands bashed the lid for a while with their mattocks until a siren blast sent them fleeing and then an explosion blew the cover open.
The shaft can be seen dimly lit, descending into the earth. We have been chosen by the council to investigate.
