Christopher grew up an orphan, but when he got older he trained to become a soldier, eventually he ended fighting alongside the prince and became friends with him.

After the war was over the prince gave him and his (at the time newlywed) wife a large sum of money to start a new life anywhere in the kingdom, since his wife was also a friend of the prince.

So he and his wife started an orphanage for all the orphans the war had caused, but unlike other orphanages it was a happy place.
