Skippius is a broad-shelled male tortle with a weathered olive-green hide and a shell patterned in muted copper, moss, and cream. His shell is crowded with carefully fitted brass brackets, tiny storage compartments, and several removable lenses that he insists are practical rather than decorative. His hands are the first thing most people notice, with thick claws capped by tiny tool guards and stained green-brown from alchemical reagents, oil, and herbal work. He keeps his head neatly shaved except for a short topknot secured with wire, and wears a spectacles-like magnifying frame over his brow even when he is not using it.

Skippius is precise, patient, and genuinely kind, though his kindness often arrives in the form of repairs, labeled instructions, or unsolicited medical advice. He has no nostalgia for a past he cannot remember and becomes mildly confused when others insist that he should feel incomplete. He is fascinated by ordinary habits, especially jokes, family traditions, and favorite foods, because he regards them as living records of identity.

Skippius awoke alone in a shallow ravine with a half-built brass device clutched in his claws and no memory of how he got there. He knew his own name only because it was engraved inside the device, along with a set of meticulous diagrams written in his own hand. The machine was broken, but its design was sophisticated, compassionate, and clearly intended to preserve life. Skippius did not mourn the person he had been. To him, a missing past was simply an unsolved problem, and unsolved problems demanded patience, tools, and repeatable experiments. He withdrew into a secluded woodland hollow, where he built a small workshop into the roots of an ancient tree. There he studied herbal medicine, repaired abandoned equipment, and gradually reconstructed the brass device. His isolation produced a strange revelation. The device was not a weapon or a key, but a memory vessel, designed to store and restore a mind. Skippius chose not to activate it. He decided that whatever truth it contained should not control the person he was becoming. Instead, he became an artificer dedicated to making useful things for ordinary people, and eventually constructed a loyal steel defender from the device's remaining components. He calls the construct Patch, because the name seemed honest.
