The Last Creature Bureau is Anthony Frederick's series about a government agency dedicated to protecting endangered species — or so it claims. Field agent Callie Venn, known as Agent 47, has spent nineteen years serving the Bureau with unwavering devotion. She wears the Bureau leather jacket with its dragon crest, carries a Model 47 tranquilizer rifle, and has polished her badge smooth from years of habitually thumbing the dragon emblem.

Her world shatters when she discovers the Bureau has been systematically falsifying extinction data. Rather than protecting species, the organization has been quietly exterminating them. The true extinction numbers — 472 species cataloged in 1887, only 152 remaining by 2003 — reveal a conspiracy far deeper than anyone suspected. Nasir Reid, the Bureau's archivist of thirty-five years, had been secretly collecting evidence of this extinction program for sixteen years before his kidnapping.

The series explores themes of institutional corruption, the violence of conservation as control, and what it means to grieve species that were never allowed to be known. Dr. Elaine Marchetti, a veterinarian at the Cascade City Animal Shelter near Sector 8's transit depot, becomes a crucial ally in exposing the truth. Julian Voss of ARKIVE Genetics operates from Spire Tower Suite 1500, maintaining active Bureau credentials while commissioning projects that accelerate the very extinctions the Bureau claims to prevent.
