Pedex was tasked with protecting the Shadow Realm after Amelia's death as a way of honoring her legacy. When Pedex senses an unnatural presence, he discovers it is Volcanic, the Fire Demon. Seeing this as an invasion, Pedex confronts him, and the two engage in a violent battle between Fire and Darkness. The conflict extends beyond the Shadow Realm and extends to the small fictional town of Oldwood, where the fighting becomes even more intense and destructive.
