Fall of Centuria

In the world of Palatovia, a demon lord seeks an ancient artifact - the Book of Stars - in the city of Centuria to gain power over the entire planet. Through his dark arts, he now commands all of the demons and other vulgar beasts - including several members of the royal family now existing as demons. Ptolemy, age 10, counts himself in their number - but the demon lord doesn't yet know the demon who was once a boy possesses what he seeks.

The demons have the upper hand in their fight against the humans on Palatovia. Lord Emalf, the demon lord, has destroyed the city of Centuria, leaving no survivors save Nydraia, a leader of the nes kaliba, a water people. Through his dark arts, Emalf now commands all of the demons and other vulgar beasts such as giant worms and flying spiders. Although he is physically imprisoned, Emalf can still manifest his form across worlds and dimensions. So many are lost or missing: Gathar's magically-inclined son, Ptolemy, age 10, has just suffered a crash-landing because the demon ship he was on was attacked by a blue dragon....
