Bonnet is a lean, tawny-furred male tabaxi with dark brown rosettes along his shoulders, back, and tail. His large ears twitch constantly toward distant sounds, and his amber eyes are bright with patient curiosity. His broad feline jaw and prominent canines show clearly whenever he laughs or eats, giving his warm smile an unexpectedly formidable edge. His hands are especially distinctive, with thickened pads, blunt claws, and callused fingertips stained by years of grinding herbs, climbing stone, and practicing open-handed strikes. He wears simple saffron and brown traveling robes, a weathered sash, and a small bundle of dried plants tied at his hip.

Bonnet is observant, gentle, and intensely curious. He prefers listening to speaking, but once a subject catches his interest, he can ask a relentless stream of precise questions. He treats injuries with calm concentration and danger with a quiet, almost scholarly focus. Although he enjoys solitude, he is deeply protective of vulnerable people and becomes unexpectedly fierce when someone uses knowledge to exploit the sick or helpless.

Bonnet was born among a wandering tabaxi caravan, where his restless curiosity made him a poor fit for a life measured in roads, markets, and stories already told. As a young cat, he followed a scent into a mountain ravine and found an abandoned monastery hidden behind a curtain of silver vines. The sole remaining monk, an elderly healer named Sister Vey, expected Bonnet to leave after one night. Instead, he stayed through the winter, then through the spring, learning that stillness could be more demanding than travel. Sister Vey taught him to turn curiosity into observation, observation into discipline, and discipline into compassion. For nearly seven years, Bonnet lived as a hermit in the ruined monastery. He cultivated medicinal plants, copied old remedies, and practiced striking hanging gourds until his paws became tough and precise. His most important discovery came when he realized that controlled breathing and pressure-point work could help draw certain poisons from the body when paired with the right herbs. When Sister Vey died, Bonnet left the monastery carrying her notes, a pouch of seeds, and a promise to bring his knowledge to people who could not reach a secluded healer. He now travels as a quiet protector and wandering physician, seeking both rare plants and the unseen causes of suffering.
