Warriors: Changing Skies

Lore & Background

Warriors: Changing Skies is set after the events of A Starless Clan. The arc begins with The Elders' Quest (7 January 2025), in which StarClan debates sending a prophecy warning of a cat with a paw in both worlds. Humans begin a building project threatening the Moonpool, though only Tawnypelt is worried. Moonpaw struggles with warrior training and a voice in her head—her dead sister Morningkit—while SkyClan leader Leafstar steps down after a badger attack kills Starlingpaw's father. Tawnypelt receives the prophecy at the book's end.

In Hidden Moon (4 November 2025), Starlingpaw learns of the prophecy and suspects cats of wrongdoing. Moonpaw continues to struggle with Morningkit's voice. The Clans send a patrol to the Tribe of Rushing Water to contact StarClan through a cat in both afterlives. Crowfeather learns the prophecy but keeps it secret. Moonpaw's attempt to get Morningkit to move on backfires, and Morningkit physically attacks her.

Chasing Shadows (31 March 2026) sees Crowfeather in a coma after an eagle attack; his spirit wonders aloud which cat is foretold to cause trouble. Starlingpaw reveals the prophecy to all Clans at a Gathering, raising tensions. Moonpaw is tormented by Morningkit, who takes control of Moonpaw's body and attacks Goldenpaw. Moonpaw leaves ThunderClan to protect others. Starlingpaw sees Morningkit beside Moonpaw and escorts her out of Clan territory. Tawnypelt organizes a quest to the Whispering Cave after human interference destroys the Moonpool's connection to StarClan.

Reader's Guide

Warriors: Changing Skies represents a significant shift in the Warriors series by directly addressing human impact on the Clans' environment, a theme that resonates with contemporary ecological concerns. The arc introduces a complex internal conflict through Moonpaw's struggle with her dead sister's spirit, which blurs the line between mental health and supernatural elements. The destruction of the Moonpool—the Clans' primary means of communicating with StarClan—marks a major disruption to the series' established spiritual framework, forcing characters to seek alternative methods of contact. The mixed critical reception highlights the arc's uneven pacing: The Elders' Quest was praised as a strong start with compelling personal struggles, while Hidden Moon was criticized as sluggish and cluttered with names. Despite this, both books achieved New York Times Best Seller status, indicating strong commercial appeal. The arc's ongoing nature leaves key questions unresolved, including the fate of the Moonpool and the true meaning of the prophecy.

Series Position & Publication Timeline

Warriors: Changing Skies stands as the ninth arc in Erin Hunter's long-running juvenile fantasy series, picking up the narrative thread left by A Starless Clan. The arc launched in early 2025 with The Elders' Quest, followed by Hidden Moon in late 2025, and Chasing Shadows scheduled for March 2026. Two additional volumes—Guiding Light in October 2026 and False Dawn in March 2027—are already on the calendar, with a sixth book yet to be announced. The series remains ongoing, meaning readers are still following its unfolding story. The arc centers on three young cats—Moonpaw, Starlingpaw, and Tawnypelt—as the warrior Clans confront an escalating threat from human development encroaching on their territories. This marks a notable shift in the series' focus, placing human presence at the heart of the conflict rather than treating it as a peripheral danger.

The Prophecy & the Moonpool Crisis

The narrative engine of Changing Skies is a prophecy delivered by StarClan to Tawnypelt, warning of a cat who walks between two worlds and risks straying into darkness. This foretelling sets off a chain of suspicion and tension that ripples through every Clan. Simultaneously, human construction work endangers the Moonpool, the Clans' sacred channel for communicating with their ancestors. Tawnypelt is the only cat initially alarmed by the threat, and her concern is largely dismissed. The situation escalates when the humans withdraw their materials, only for the Clans to discover the Moonpool's spiritual connection has been irreparably severed. Tawnypelt then organizes a quest to the Whispering Cave in SkyClan's former homeland as an alternative means of reaching StarClan. Meanwhile, the prophecy's ambiguous wording fuels paranoia, particularly in Starlingpaw, who becomes convinced he is the foretold troublemaker and begins suspecting those around him of hidden wrongdoing.

Character Struggles & Shifting Alliances

Each of the three protagonists carries a deeply personal wound that shapes their arc. Moonpaw is haunted by the voice of her deceased sister, Morningkit, who refuses to pass on to StarClan and instead torments her from within. Moonpaw's shame and fear keep her silent about the intrusion, and her warrior training suffers as a result. When Morningkit's jealousy over Moonpaw's affection for Goldenpaw drives her to possess Moonpaw's body and attack him, Moonpaw flees ThunderClan to protect others. Starlingpaw, grieving his father's death caused by Leafstar's failed judgment during a badger attack, becomes consumed by the prophecy and watches Crowfeather's spirit question which questing cat is the dark one. Tawnypelt, meanwhile, navigates the political fallout of Leafstar's resignation and the loss of the Moonpool, ultimately reconciling with Tigerstar after a falling-out and taking on the leadership of a desperate quest.

Critical Reception & Commercial Performance

The arc has drawn sharply divided critical responses. Kirkus Reviews hailed The Elders' Quest as a strong opening, singling out the way it lets each main character grapple with distinct personal struggles. However, the follow-up, Hidden Moon, earned considerably harsher criticism from the same outlet, which described it as sluggish, overburdened with named characters, and uninspired. Despite the mixed critical verdicts, commercial performance has remained solid. The Elders' Quest spent three weeks on the New York Times Best Seller list by early February 2025, and Hidden Moon reached the same list for a week by late November 2025. The contrast between the two books' reception suggests the arc is still finding its narrative footing, with the first volume establishing stakes and character depth while the second struggled to maintain momentum.
