The first title The Black Elfstone was released on June 13, 2017. Set about 200 years after The Defenders of Shannara, long years of peace comes to an end as mysterious invaders show up in the Northlands. These invaders use a magic that nobody, not even the Druids, can recognize and have unknown intentions towards the Four Lands. A delegation of Druids is sent to investigate under the protection of Dar Leah.
Meanwhile, former High Druid Drisker Arc has to deal with assassins as well as a young girl named Tarsha Kaynin who has sought out his guidance. Tarsha has the power of the Wishsong as does her brother Tavo...who is driven mad by its power.
These books contain examples of the following tropes:
- Bookends: The first book The Sword of Shannara (in publication order, not in-universe chronological) features a character named Shea Ohmsford. The Black Elfstone features a character also named Shea Ohmsford.
- Grand Finale: Intended to the final chapter in the entire Shannara franchise though Brooks hasn't ruled out doing other works set in the Shannara universe.
- Kill It with Fire: How the assassins attempt to take out Drisker; they set fire to his cottage.
- Legacy Character: The Varfleet youth that helps Drisker locate the assassin guild; he reveals his name as Shea Ohmsford.
- Meaningful Name: This set of books is called ''The Fall" for a reason; it's the conclusion.
- The Mole: Kassen Drue. He joins the Druids as a trainee but is working for the mysterious invaders. He lets the invading army into Paranar where they completely destroy the Druids and their Troll guards.
- Morton's Fork: Drisker catches up to Tigueron of the Orsis assassin guild to learn who hired them. Drisker threatens to kill Tigueron if he doesn't reveal the name of his employer. Tigueron replies that his employer will kill him anyway if he talks. Tigueron identifies him as Kassen Drue but Drisker kills him anyway to make sure no more assassins attack.
- Mugging the Monster: Tavo has the power of the Wishsong, which any Shannara reader would recognize as a destructive weapon if used so. Tavo keeps encountering bullies and robbers who seek to hurt him; guess how that turns out.
- Persona Non Grata:
- Drisker Arc; he's banished from both Paranor and the Druid order after he steps down as High Druid.
- Tavo Kaynin; his parents send him away because of his reckless violent behavior and put him with an uncle who tortures and imprisons Tavo in a shed.
- The Worf Effect: The mysterious invaders encounter two armies of Trolls, renowned in the Shannara universe as without equal on the battlefield. The invaders easily annihilate both armies of Trolls down to the last.
