Guardians and Allies

Luna's best friend, exactly two years older than her. Messy brown hair, a wide smile, attentive eyes. He is the group's documentarian: he records everything, and he is practical, curious and always ready to improvise. His smartphone is his first tool, but he learns that analog solutions are more reliable when the network fails.

• Skill: Technical Improvisation
• Gear: Smartphone (compass, flashlight, camera)
• Accessory: Navigator's Medallion

AMI is a three-hundred-year-old backpack that holds the archive of the ancient Guardians and materializes the exact instrument when asked precisely and out loud. It has been with Luna ever since her grandmother Rosa handed it to her. It is the bridge between ancestral wisdom and scientific knowledge.

• Function: Guardian Knowledge Archive
• Ability: materializes instruments on precise requests
• Origin: a gift from Grandma Rosa

He appears in the Ember Plains as a boy the same age as Luna and, year after year, he seems to grow at exactly the same pace she does. Tousled brown hair with a hint of moss, brown skin and eyes that look far older than his face. He smells of wet earth even under the sun, and his surname, Tierra, literally means Earth. Who is Gael, really? That question stays with Luna, and with the reader, across all five books.

Rosa Mendoza, the original Guardian and Luna's grandmother on her mother's side. Silver hair in a braid, wise eyes with smile lines. She wears a shawl woven with natural symbols. Her own gift awoke when she was 12. She teaches Luna that science and intuition are two sides of the same coin.

Luna's mother and a geologist at the National Institute of Geology. She studies the movements of the Earth with instruments, maps and a lot of patience, and her scientific knowledge complements her daughter's intuition. Decisive and practical, she always finds solutions where others see problems. In the Solari home, science and the gift walk side by side.

Luna's father and a member of Equandia's Search and Rescue Team. He grew up in a family of artisans, between carpentry and blacksmithing, and that is why his hands can fix almost anything. He cracks jokes even in the worst moments, not because he doesn't grasp how serious things are, but because he discovered that calm rescues people too. He sees every problem as a puzzle to solve.

Mateo is the freckled boy in the front row at the Spring Village school. At first he laughs at Luna like everyone else. But when the ground truly shakes, he is the first to come over and ask, without mocking, how she knew.

From then on he names himself her official helper. His motto: “I'd rather you warn us ten times and nothing happens than not warn us once and something does”. How far can a helper who never stops believing go? That unfolds book by book.

Ana lived three hundred years ago, in the days of the Broken Silence. Like Luna, she felt what the Earth was trying to say; and like Luna, she tried to warn the grown-ups. She wrote it all down in her diaries: every signal, every warning, page by page.

Three hundred years later, those diaries still exist. What do they tell? Why do they matter so much? And what connects Ana to Luna? Her story unfolds in Echoes of the Past.

An 8-year-old girl, curious and hopeful, who crosses Luna's path just as the story enters its most decisive stretch. Why does the Earth seem to notice her? What Nova means for the future of the Guardians is one of the secrets of The Awakening of the Five.

A presence of shadow and smoke with bright amber eyes that appears when people stop listening to the Earth. It is not a villain: it is a mischievous force of change, swirling like the wind, smiling when no one expects it and testing the Guardians. What Umbra is, where it comes from and what it wants is one of the mysteries the series reveals book by book.
