A great battle begins on Ravnica... Teyo Verada just wants to become a shield mage and, controlling magical powers, protect his people from the cruelest diamond storms of his home world. But then, after the first real storm, he was buried alive in the sand. A little more, and the life of the young magician would come to an end before it really began... but that was not the case. A certain power, an ability that he did not even suspect about, instantly transports him to another world - to a world of metal, glass and miracles, to Ravnica. Yes, Teyo is a planeswalker, one of many summoned to a city that stretches from one end of the world to the other, all lured there by the Ancient Dragon Nicol Bolas. Aspiring to the highest peak, hungry to become a deity, Bolas lays siege to Ravnica. His unrivaled magic and unstoppable warriors threaten to turn the great city into ruins. Among those who stand ready to thwart Bolas's horrifying plans are the Guardians, planeswalkers sworn to destroy evil wherever they encounter it. But as they try their best to unite other mages to stand up for Ravnica and its inhabitants, the terrible truth about Bolas's plans becomes clear as day. On Ravnica, the Ancient Dragon has prepared a trap - a trap for the most powerful magicians of the Multiverse, and there is nowhere to run. So, forces - large and small - are drawn to the battlefield, the battle begins, and the stakes are higher than ever. If the Guardians fail, if the Planeswalkers fall, the age of heroes will come to an end, and when the curtain rises again, a completely different drama awaits the Multiverse - the drama of the endless reign of Nicol Bolas.
