Sephro: Back to Earth

The war between Sephro and the terrible Lorianna and Jondu is over. Earth and Sephro have united as Cryss Slattery, witch of Earth and Craela of Sephro, married and had two twins. The rest of Sephro, including its other Earthan inhabitants couldn't be happier. However, Craela can't stop going into the astral world to chase a strange cloaked figure who is, for reasons she can't explain, important to her. When the figure goes into a tunnel and Craela follows soon afterwards, she is suddenly face to face with a darker, more sinister side of planet Earth. Could this threaten the once-powerful unity between the two planets?
