Fantasy is the most demanding genre when it comes to consistency. Magic systems must hold their rules across hundreds of pages. Characters with fifteen abilities and three rings can't suddenly have different eye colors in chapter 30. Worldbuilding details from book 1 must still apply in book 5.
This tutorial series gathers the craft you need — from the first idea to the finished series. Worldbuilding without getting lost in details. Magic systems that hold. Fantasy names that don't sound generic. The hero's journey as a tool, not a dogma. Cozy fantasy and romantasy as current trend currents.
