G_Thang,
Maz Kanata is this female alien who was a pirate. She may have Force powers. Supposedly, there is a scene where she conducts a flashback/vision using her powers. This is when we first see Luke Skywalker.
He is in the vision, not the room.
It seem that she knows Han, Leia and possibly Luke.
The character is being played by Lupita Nyong'o. That's the girl from 12 Years a Slave.
But she will be all Mo-cap/CGI. The little picture is from the Official Poster.
Oh, and she is in the second teaser. She hands Luke's lightsaber to Leia.
Here's a picture.
“Her history is that she was a pirate for a long time. She’s lived over a thousand years. She’s had this watering hole for about a century, and it’s like another bar that you’d find in a corner of the Star Wars universe.” - JJ Abrams
