The Rising of The Half Demon

If an angel can fall... then why cant a demon rise. It’s the year 154 of the demon age in a world overrun by demonic creatures and beings, so much so that only a handful of cities remain left on the planet. The angel’s abandoned the people and no one knows where they went or if they will ever return. Each city has its own distinct culture and beliefs and some are completely shut off from the others while the majority of them have open borders and have free communication and transport via teleportation circles left by the angels before they vanished. In this world a wise young half demon girl pairs up with a witty, lighthearted, but sometimes deadly serious Half dwarf to try and unite the cities to take a stand against the demons and take back there land that once flourished.
