Earth also known as the Dayside is the home of the Human race and was to be invaded by an alien race called the Nekross who wished to harvest the planet's Magic. However, Wizards protected the planet from an invasion.
It has a parallel world called the Neverside which is home to magical creatures and the old home of Wizards. The two worlds have different time zones e.g. a few hours in the Dayside is 20-30 years in the Neverside.
