Land Bridge
Recently, a path has been discovered connecting all of the islands on Magi, it winds about in the water, around three feet out of the range of the lapping waves. It makes for fairly calm seas all about. Close to 30 feet wide, there is plenty of room to travel two wagons side by side. It is by this "Land Bridge" the unicorns and the un-bonded get to the other islands, for whatever reasons. It's fairly safe traveling, so long as the skies are blue and the water's calm.
