I don't know how much thought Dave Arneson's gaming group put into these scenarios, but there were several of them where they wanted to try out their Blackmoor characters against WWII type opponents and possibly opponents from other eras as well.

I have assumed that these were seen as visits to other dimensions, but what if we retconned them into being time travel scenarios on the planet of Blackmoor instead? Dave Arneson described some of their opponents as Nazis, but could we reimagine them to be Thonian fascists from the future? How would this fit into established fan timelines?

How many examples do we have of original campaign characters travelling to places which could be interpreted as different places in time?
