Here is a Picture of the surface of Alderan that planet which was destroyd in Episode 4 by the Death Star. This is the capital city of Aldera. The planet itself is covered in grasslands and small inland seas. Its a very interesting World. This is the place where Lea Organa grows up The leader of the Rebellion. This too is a conceptual painting that was made by artist Ralph McQuarrie. He did this during the original trilagy.
