Rusty is the undisputed patriarch of his mob, a massive red kangaroo whose rust-colored fur and battle-scarred ears tell the story of decades surviving the Australian outback. He has fought off rivals, outlasted droughts, and led his mob to water through landscapes that would kill lesser creatures. Despite his imposing size and fighting history, he is remarkably tolerant of non-threatening company, often allowing birds to perch on his back and approaching humans with a cautious but curious calm.

Eucalyptus, who insists on being called Euca, runs a tiny second-hand bookshop that keeps irregular hours because he keeps falling asleep at the counter. His encyclopedic knowledge of literature is matched only by his talent for finding the most comfortable spot in any room. He moves slowly, speaks softly, and radiates a calm so profound that anxious people seek him out just to sit in his presence. He has never once been in a hurry and cannot fathom why anyone would be.
