This downloadable product includes five villain NPCs. This chapter picks up right where "Prologue: The Silver Storm" — the prologue to Emerald City Knights — left off, with the heroes dealing with the aftermath of the strange explosion that has unleashed something new and dangerous in Emerald City.
