So running a Frozen Skies campaign gives me the opportunity to try stuff out beyond the typical scope of a one shot adventure. One of the ideas that I wish to develop and playtest is expanded rules for airships and combat involving them. This will of course feed into Skies of Crimson, the next book that is planned for Frozen Skies.
