A few years ago Eric and I talked about doing a 1632 WarSpell crossover. The idea was that a bunch of gamers playing WarSpell would set their game in a copy of the 1632 universe, but with a little bit of magic. Paula and I wrote the book and then Eric decided that he didn't want to do the crossover. The story was fine and Ring of Fire Press would have published it, but he wanted it changed so that it was no longer a 1632 crossover. That was because he didn't want people starting to think that this was part of the 1632 Canon, At the time I had been thinking that I would have to change ...
