So, the War of the Spark is over... and its end marks the beginning of the hunt for Liliana Vess. The victory over Nicol Bolas and the salvation of the Multiverse cost the Planeswalkers considerable losses. Now the living must deal with the consequences and mourn the dead. But one of the losses is especially, unbearably bitter: the triumph cost the life of the knight of justice, the pillar and shield of the Guard, Gideon Jura. While his former comrades, Chandra and Jace, try to recover from such grievous grief, their future, like the future of the Guardians, remains unclear. New member of the Guardians, Kaya, seeks to help them create the future. Joining the ranks of the defenders of the Multiverse, she swore an oath to protect both the living and the dead, and her oath is almost immediately put to the test. The grieving guildmasters of Ravnica entrust Kaya with a serious task - one that matches her gifts as a hunter and killer, a task she is ordered to keep secret from the other Guardians. She must track down and execute the traitor Liliana Vess. However, Liliana Vess does not want to be found. Rejected by her friends, she flees Ravnica immediately after defeating Bolas. Hostage to the evil will of the Ancient Dragon, the necromancer was forced, under pain of death, to help Bolas in all his atrocities, until Gideon - the last one who believed in the nobility of her soul - sacrificed his life, saving Liliana from death. Tormented by Gideon's last gift, pursued by her former allies, Liliana returns to the lands she never thought she would ever see - home. She has nowhere else to go.
