Across the vast Multiverse, those gifted with a “spark” can tap into the raw power of Magic and travel across realms — they are Planeswalkers. When coordinated assassination attempts on Guildmasters Ral Zarek, Vraska, and Kaya rock the city of Ravnica and leave Jace Beleren’s life hanging in the balance, a fuse is lit that threatens not just these three Guilds, but the entire plane of Ravnica. Now these three must covertly infiltrate the wild plane of Zendikar and form a tenuous alliance to uncover why the targets of the assassins have all been Planeswalkers. . . which will lead them straight to one of the most enigmatic characters in Magic history!
