I do not know a lot about the Dark Ages, other than they mostly were not dark. I purchased As Told in the Great Hall: A Wargamers Guide to Dark Age Britain by Martin Hackett years ago to help out (at least for Britain). It is a good read, and also contains some dark age scenarios. I meant to use them back in 2014 but never got around to it. November 2020 approached and I had a revised plan. Play all the scenarios using my own rules, and play them on a 1’x1′ board with my own rules so I have a chance to complete them all in one month.. I played 15 out of the 17 scenarios in the book (2 were not suitable for the rules). I did complete this in November but it has taken me this long to find time to write it up.
