The title's pretty self explanatory, but I'm wondering who the "Oliver" is that is spoken of in the general event cards. For instance, it says on one card "Move Oliver to such and such"... blah blah etc. There's no mention of an "Oliver" in the manual, and as far as I can tell, there doesn't seem to be any sort of physical representation of him. So my either/or question is 1) What does this phantom Oliver piece look like and what's the deal with it? or 2) Why is there explicit instructions to "move" him if there is no physical token of him and he's ultimately irrelevant?
