There is no sun in this different world, this other place.  All there is now is a gentle rolling sea, and crystal clear blue skies, that reflect the deeper blue waters of the western sea.  Maybe it is the sea  that reflects  the clear blue of the skies.  The Ship moves straight toward a far off place, an unknown place.  The air is clear, brisk, and invigorating, as if it has a life of its own.
