Abelard, known casually as Abel, is a wealthy, genteel mouse who relies on a family inheritance and is unaccustomed to physical labor or discomfort. When a sudden storm sweeps him away and leaves him marooned on a deserted island, he faces immediate physical and emotional trials. Stripped of his fine clothes and leisurely lifestyle, Abel must tap into primal animal instincts to build shelters, forage for food, and survive the elements. He relies on his intelligence and imagination to maintain hope while isolated in nature.

Amanda is Abel's wife of one year, described by her husband as a dreamy mouse who often seems lost in her own thoughts. She represents the safety, warmth, and love of home that Abel desperately longs for while separated from his community. When a fierce gust of wind blows her scarf away, it sets off the chain of events leading to Abel's isolation, turning the scrap of fabric into a powerful symbol of their enduring bond.

The Owl is a relentless predatory bird that claims the island as its hunting ground during the harsh winter months. It poses a severe physical and psychological threat to Abel, driving the small mouse to craft weapons and perform mystical incantations out of fear and desperation. The bird acts entirely on animal instinct, showing no mercy or emotion.

Gower is an amphibious frog who accidentally lands on the island after being caught in swollen floodwaters. Though his crude, creature-like habits sometimes shock the refined Abel, Gower proves to be a lively and charming companion. He has a large family of his own and is highly anxious to return to them.

The Cat is a dangerous feline predator that crosses paths with Abel during his travels. Driven by natural hunting instincts, the cat presents a direct threat to Abel's life, testing the survival skills and physical strength the mouse has developed during his isolation.
