The Courts of Chaos is a fantasy novel by American writer Roger Zelazny, the fifth book in the Chronicles of Amber series.

The next series begins with Trumps of Doom following his son, Merlin, as the protagonist.

Corwin must ride the entire length of the multiverse, from Amber to the Courts of Chaos, while Oberon attempts to repair the Pattern.

Corwin sulks in Castle Amber's library while Oberon gives the family orders.

Once Corwin confirms Dara's authority, Benedict uses the trump of the Courts of Chaos to begin his attack.

After a time, he notices the black road begin to come apart; shortly after, the raven arrives and gives him the Jewel.

The real Corwin dismisses this story as unhelpful and commands the Jewel to quell the storm.

He says goodbye to the stranger and tracks his horse to a cave, blocked off by a large boulder, which he shatters.

Succumbing to their odd charm, he starts to fall asleep, but rouses himself in time to see them preparing to slaughter him.

As he leaves, the leader of the wee folk recognizes him as the Archangel Corwin from local legends, mentioned before by the nameless stranger.

He realizes that the storm was a wave of Chaos, moving away from Amber as the multiverse is destroyed.

As the metaphysical storm approaches Chaos, Corwin decides that Oberon must have failed, so he plants his staff and begins to use the Jewel to inscribe a new Pattern.

The process evokes memories of his former life in Paris, France, and is given the impression that these somehow shape the new Pattern.

Corwin recognizes him as Master at Arms of the Courts of Chaos and the teacher of Dara in swordsmanship.

Suddenly an image of Oberon fills the sky, telling them that Corwin must use the Jewel to save them from the oncoming Chaos storm, leaves the question of succession "[up to] the horn of the Unicorn", and gives them a blessing.

They watch Amber's armies crush the forces of Chaos while the storm continues to advance.

A funeral procession, led by Dworkin, emerges from the storm front, accompanied by all sorts of fantastic beasts.

Corwin discusses with Fiona the possibility that two Patterns now exist; she can't decide whether that is good or bad.

It examines each of the Amberites in turn, then kneels in front of Random, presenting him the Jewel, and in accordance with Oberon's message, the succession.
