You've opened my eyes to something I never thought possible, final fantasy and Star wars are related to one another. In Return of the Jedi when Luke's father is killed, he isn't dead and goes to the after life. The after life isn't what he expects because it is in fact the world of Final fantasy 7. Once there though he became the shadow behind everything and secretly built walkers but you can't see them because they're invisible. They can only been KIND of seen through a reflection of a certain sword which is that sword!
