The book itself

The book smells faintly of warm copper and bitter orange.
Its diagrams show tools and bodies as assemblies of parts, never as finished things.

The caster

  • ArtificerMara Vellum
Studies: Transmutation and practical alchemyManner: Courteous and quietly intense, she treats every unfamiliar object as a problem worth understanding.Focus: A brass caliper with a removable crystal stylus, used to measure, inscribe, and channel her spells.Quirk: She taps objects twice with her caliper before trusting them, even when the object is a chair she has just made.Wants: To discover whether a material can be given a stable new nature without destroying what it was before.Mara Vellum apprenticed as a clockmaker before turning to artificing. She became fascinated by the boundary between repairing an object and changing what it is. Her folio is a record of experiments, field repairs, and costly mistakes.

The book

A brass-clasped, oilskin folio whose hammered copper covers are embossed with changing anatomical diagrams. Its pages are vellum, thin metal sheets, and pressed leaves, all annotated in a precise hand.

Plot hooks

1A page describing a metal alloy that can repair itself has been torn out. Mara suspects a rival artificer stole it to build an army of self-mending constructs.
2The folio’s shifting diagrams begin depicting a ruined observatory that Mara has never seen, along with a transformation formula she believes could reverse a decades-old petrification.
3A guild claims the folio’s notes prove Mara unlawfully transformed a sacred monument. The monument has begun changing shape again.
