If you go on the object page and click edit it allows you to change the blurb for all the objects. My question: Does that affect the blurb on the original object page, or does it only change the object description for this game? In the latter case it would be a good place to describe just how all these are connected outside of the main text...

It only affects the description used to describe the object as it applies to this game. If you leave it blank, it shows the default blurb.

But you've probably figured that out by now.
