This sketch artifact description is also part of 'Ken Writes About Stuff Vol 1' (and you should consider to rather by that). It is a interesting and thoughtful read with good ideas how to introdruce the artifact in a campaign or to set up a whole compaign around the artifact.
However, it is only a sketch and only one artifact. Nothing more and nothing less. Kenneth Hite has tons of clever ideas (and famous historic knowledge). But AFAIK, he was not written a full-blown advanture and/or campaign so far. That's a real pitty!
If you looking for ideas and/or some inspiration to chisel a campaign on your own (or you are VERY good at improvisation) this might be all you want.
