The future is never bright in the world of Sci-Fi, if you're human. So what will we leave behind or better still take with us on the way out of Dodge?
The Last Earth Object set is a stage for those choices to play out. Several water tanks capable of holding ocean life or the last clean drinkable water of a dying planet. A central hub for holding an object in a suspension field or load one of the included props. Your world, so it's your choice.
