Question

[.:Sam:.]

Is the Valley of the Dark Lords, Korribon based on the Valley of the Kings in Egypt?

Wookieepedia has this to say about it:

 

The Valley of the Dark Lords was most likely based on the Valley of the Kings in Egypt. Indeed some structures resemble Egyptian statues

 

Nothing official, but there's a good chance those who depicted the Valley got their inspiration from the Valley of the Kings.

Plus, the ancient Sith Lords (Full and Half-breed Sith species) tended to wear Jewelry, Robes and there facial hair much like Egypt's pharaohs, so I'd say yes.
