I recently transferred my Dark Age figures for Hordes of the Things (HOTT) to Big Bases. Magicians, beasts, clerics, hordes, that kind of thing, making Big Base HOTT. This included my Strathclyde Welsh (Northern Cymry) for Britannia 600 AD.
To celebrate the big basing, Chris Harrod and I had a game of Arthurian HOTT. Chris brought along his Picts and we used sabots to give him big bases.
