D'k tahg Valley

D'k tahg Valley was a region on Qo'noS. It was also a popular shooting location for Klingon films and television shows and, as such, it was home to much of the Klingon entertainment industry. It was largely considered to be the Klingon Empire equivalent of Hollywood in 20th century and 21st century Earth. However, it wasn't, by itself, a constituency important enough to be represented in the Klingon High Council on its own.

Qo'noS 90210
Qo'noS 90210 was shot in an area known to non-Klingons only as 90210. Unlike D'k tahg Valley, it made an attempt to have a cast of characters picked from a cross-section of Klingon society.
