We are in the process of getting advice on details such as the likely vegetation and weather patterns that will be caused by the geography, from people who know this stuff better than we do. We are also looking into the physics behind having two moons. We really want to get this stuff right.
Kyrdalm is also inspiring a lot of writing in the areas of history, society, language, religions, and so on. We are trying to evolve these areas simultaneously, so that they are all properly influenced by the others. Plans are to fully develop two or three of the continents, partially develop a couple more, and leave the rest mostly to the GMs imagination.
