Saga is an epic space opera/fantasy comic book series created by writer Brian K. Vaughan and artist Fiona Staples, published monthly by Image Comics. The series is heavily influenced by Star Wars, and based on ideas Vaughan conceived both as a child and as a parent. It depicts two lovers from long-warring extraterrestrial races, Alana and Marko, fleeing authorities from both sides of a galactic war as they struggle to care for their newborn daughter, Hazel, who occasionally narrates the series.

In a city so dismal it's known only as "the Hole," a clan of Sorcerers have been plucking people off the streets to use as guinea pigs for atrocious "experiments" in the black arts. In a dark alley, Nikaido found Caiman, a man with a reptile head and a bad case of amnesia. To undo the spell, they're hunting and killing the Sorcerers in the Hole, hoping that eventually they'll kill the right one. But when En, the head Sorcerer, gets word of a lizard-man slaughtering his people, he sends a crew of "cleaners" into the Hole, igniting a war between two worlds.
