Yoshi said not everything will be implemented at launch. That may be why they took some pics off the official site. Some things may be quest related and SE is suppressing anything that gives away any part of the story line.

Personally I think suppressing the story is a bad idea. ESO is releasing a ton of stuff on storyline and fans are going gung-ho over it. Releasing info is not the same as experiencing the actual events in-game. I think SE is being too tight lipped.
