Maz Kanata

Maz Kanata was a female alien of an unknown species and a pirate who lived for over one thousand years. She owned a castle on the planet Takodana, and somehow came into possession of Luke and Anakin Skywalker's old lightsaber. She was an old friend of Han Solo's and was fond of Chewbacca. She had the ability to sense force-potential in others, and discovered that Rey was force-sensitive and had potential as a Jedi.
