The Ravnica Cycle is a trilogy of tie-in novels by Cory J. Herndon, set on the eponymous City Plane of Ravnica, that corresponds to Magic: The Gathering's Ravnica block.Each of the three novels is mostly self-contained:
Ravnica: Agrus Kos, a wojek officer, is investigating the death of his partner, with the help of said partner, who's been Resurrected for a Job. Fonn is a rookie ledev in the Selesnya Conclave, escorting an important dignitary to the capital. Jarad is a devkarin elf who holds a high position in the Golgari Swarm. Their paths collide when they stumble upon a conspiracy that threatens all of Ravnica.
Guildpact: Agrus Kos is retired and living a quiet life in the wild, untamed Utvara district, which has recently come under the management of Orzhov heiress and advokist Teysa Karlov, who intends to shake the place up. Meanwhile, the Izzet courier Crix gets lost and is captured by a clan of Gruul barbarians. When a mad scientist threatens to destroy the world, they'll all have to work together to stop him.
Dissension: After mysteriously disappearing in the first book, the angels have returned...and they're all dead. Meanwhile, another conspiracy rears its head, and Agrus Kos is raised from the dead to investigate it. On top of all this, the city is being destroyed by giant monsters.
Ravnica, Guildpact, and Dissension contain examples of:
Abandoned Warehouse: Agrus Kos and Myczil Zunich investigate one at the beginning of the first book.
Becoming the Costume: Thanks to a faulty "performance enchantment", a troupe of actors wreaks a little accidental havoc in Chapter 2 of Ravnica when the guy playing a bloodthirsty Gruul chieftain gets a little too in-character.
Body Surf: Kos does a fair amount of jumping about in Dissension.
The Cavalry Arrives Late: In the final battle of the first book, Sunhome and the angels are nowhere to be found. They don't return until the end of the next book, and we don't find out what really happened until 'Dissension''.
Moral Sociopathy: The Azorius, who care more about laws and order than about the common people the laws are supposed to protect.
My God, What Have I Done?: Myczil Zunich's approximate reaction when he discovers that he's just accidentally killed a little girl.
Nice Job Breaking It, Hero: Dissension takes a chapter, or thereabouts, to explain that the reason why the plane of Ravnica is so horribly screwed up is because Agrus made it a point to arrest Szadek as a member of the Boros Legion. Minor problem with that, though: the Guildpact was designed to maintain the existence of all ten Guilds. Without House Dimir, the Guildpact was actively screwing up.
Only Known by Their Nickname: Feather, aka Pierakor Az Vinrenn D'rav. At least to most people; the other angels and officials like the Azorius tribunal use her real name.
Xanatos Gambit: Szadek's plan. Plan A: Get Savra initiated into the Conclave, then kill her, destroying the rest of the Conclave with her, thanks to the mind link. Without their power upholding it, the Guildpact will be shattered. Plan B: The Conclave recovers in time and the Guildpact is not destroyed, but Szadek's defeat and subsequent arrest breaks the balance of power in the Guildpact by removing the tenth guild, causing it to crumble anyway. Either way, the Guildpact is destroyed and Szadek wins.
