Harry Potter has become one of the best-loved transmedia characters since his first appearance, and J.K. Rowling has created a transmedia franchise composed of media and narrative expansions and their resulting fandom practices. This chapter discusses the transmedia affective strategies present in the Harry Potter franchise, and analyses the construction of this expansive story world – specifically, the relationship between cultural death representations and postmodern sacred elements of our pop culture spirituality. Thus, Harry Potter has become a cultural icon that underlies a diversity of deep cultural and political discourses. These are constructed through pop culture spirituality, which is a narrative framework where cultural signifiers, magical beliefs and spiritual experiences function as a narrative basis. The fandom practices and the identification of the audience with the transmedia character contribute to the mythos, the topos and ethos of the franchise.
