DiaryThe hinge was only iron yesterday. It has learned to remember the shape of a key.
FormulaCopper salts + measured heat + patient agitation: the stubborn alloy yields.

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.

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.
