I am planning to include a very big plot line to my third fantasy book. After the Dark Death plague ravaged the Empire and the Sword of Power was lost, magic mostly disappeared and most of the bloodlines of Druid sorcerers lost their power. Only two Druid bloodlines kept their power, but they were shadows of their former selves. This absence of magic had been going on for over three hundred years until the Sword of Power was rediscovered in Numen the Slayer. This along with other factors will lead to a resurgence in magic and the Empire will never be the same again. I will be seeing a magic show in Las Vegas in two weeks so that should give me some ample inspiration.
