4 notes
WarningA willing heart is not a component. Ask first, even when the machine says otherwise.
DiaryThe brass lark sang the tune perfectly. It still could not tell me why she was sad.
FormulaThree turns clockwise for calm; never use the fourth notch unless the listener asks to forget the room.
DiagramThe ring of sympathetic filaments should face inward when cast on a willing ally.
The book itself
The book smells faintly of beeswax, hot copper, and rosewater.
Its enchantments are built as delicate devices, not effortless commands.
The marginal symbols resemble music notation, though none of the melodies are written down.
The caster
Artificer, resonance engineerIlyra Venn
Studies: Resonant enchantment through engineered charms and sensory devicesManner: Warm, attentive, and precise; she asks before testing any device on a person.Focus: A silver tuning fork wrapped with copper wire, used to set the resonance of each crafted enchantment.Quirk: Taps a three-beat rhythm on her thumb before making a difficult decision.Wants: To find out who has been copying her resonance designs and using them to manipulate witnesses.Ilyra Venn apprenticed as a clockmaker, repairing the little mechanisms used in theaters to cue actors and calm nervous performers. She turned that craft toward enchantment after seeing a frightened crowd nearly trample itself during a fire.
The book
A pocket-sized brass-and-ivory folio bound with rose-colored leather. Its etched pages shift into neat diagrams when touched, and a tiny music-box heart ticks beneath the cover.

Plot hooks
1A patron offers a fortune for the folio’s original tuning fork, claiming it can calm a crowd. The fork was made from a bell stolen from a besieged city.
2One of the folio’s devices has begun repeating a melody associated with its former owner, a missing artificer whose memories seem to be threaded through its enchantments.
3A guild apprentice is accused of enchanting a judge. The folio’s diagrams suggest the device used was copied from one of its pages, but the copy is missing a crucial safety measure.
