When does Spellbinder return?

The series follows the adventures of Sydney high-schooler Paul Reynolds as he is accidentally stranded in a parallel world where the industrial revolution never happened. Only a small number of people there have technology – the "Spellbinders" – and they pretend it is magic and use it to rule over everyone else. Paul, with the help of a local girl called Riana, uses his wits and his own knowledge of science to survive.
