Legend
For the civilization/Birthright part, develop a city on the nature continent. Perhaps the PCs find the ruins of the last city civilization tried to start there and can use it as a start. Have some sort of monster there that needs to get dealt with before ships from the homeland can come with settlers. Also have several options that the PCs can do that will add to the success of the city.
Maybe there are some neutral pirates up the coast that can aid them if dealt with or a mine for ore that needs to be taken control of first. Come up with several ideas for the group to try to do that will boost the chances of building a city to base out of on the new continent. Give the group choice and let them know that they cannot complete all of them before the next season comes and the ships arrive.
You also talk about one of the kids playing a druid. If he is mature enough, try to have a NPC try to bring him to the other side and support the nature gods. It would be what people traditionally think, but it can be worked for him to be on the other side.
