Here is the story of the lightsaber:
A 47 year old on the Cloud City Janitorial Staff was cleaning out the central-vac system one day and was like, "Hey, this must be why the suction in hose 53 was so low" as he pulls out a gleaming metal tube packed with lint. "I've heard about these things", he exclaims as he sticks it in his pocket. He kept it for a number of years, displayed above his fireplace mantel. Then, one day he hit a bit of a rough patch. The Cloud City was becoming more and more automated and started laying off some of it's work-force. When his wife found out he was being laid off, she asked for a divorce. Facing the prospect of being jobless and having to go through a costly divorce he decided to sell the lighstaber he found, because it had absolutely no sentimental value and just looked like a cool conversation piece. He took the lightsaber to a pawnshop and got 400 galactic credits for it...
One day Maz Kanata was in a pawn shop and saw a lightsaber and was like "Oh man, I haven't seen one of these in a while. I should pick one up so I can pretend to be a jedi in my castle basement".
The end.
