This story is a sequel to One Moon

After finally meeting, Prince Artemis and Princess Luna now have to discover how they reached each other, and what truly occurred that fateful night. As they investigate how their two worlds are connected, however, they find that isn't the only connection they have formed.

Prince Artemis is faced with a conundrum. His brother, Solaris, seems to be contacting an alternate dimension through magical dreams, and covertly meeting with an Alicorn Princess that bears a striking resemblance to him. Inspection of this causes the lunar prince to run into somepony he never will forget... himself.
