These are all empty pages. They look characteristic to pages that were not designed to be there or linked to. A bug rather than a feature.
How do you navigate to these pages from the starwarsanswers.com homepage? I don't see any of those listed on the right hand margin. Sure, they may have been exposed because of a deployment error early on that has now been fixed.
Looks to be a basic website error than something attributable to malice.
