The 2 Wolf Tribes

Long ago, there were 2 tribes, Day and Night. Along with these tribes came 4 more, Cloud, Star, Sun, and Moon.
Each of the Day tribes had a prince and each of Night tribes had a princess, as tradition.
These tribes were great friends, for many years. That is before a war broke out.
In fear that these princes and princesses would get hurt. They sent them to another world, the same world, our world.
