WarningThe final phrase is theory, not a prepared spell. Ninth-circle magic is beyond my present reach.

The book itself
The book's silver ink glimmers when a spell is prepared.
Its final pages study the theory of a lethal word of power, but the working is incomplete and far beyond its owner's present skill.
A small brass index tab marks each spell by school and level.
The caster
Wizard, School of AbjurationMira Venn
Studies: Abjuration, with a scholarly fascination for the theory of power wordsManner: Courteous, observant, and unhurried, even when danger makes everyone else speak too quickly.Focus: A narrow brass wand with a silver thread wound around its grip; she also traces spell diagrams in the air with a gloved finger.Quirk: She silently counts the syllables in other people's names, then writes down any unusual sound.Wants: To locate the vanished wizard's observatory and determine whether the lethal word recorded in its margins can be resisted or safely studied.Mira Venn apprenticed as a cataloguer in a royal archive, where she learned to regard every spell as a precise argument with reality. She built this codex from the notes of a vanished court wizard.
The book
A midnight-blue codex bound in blackened brass, its pages ruled with fine silver lines like a star chart. Near the back, a page of immense, unfinished lettering is sealed beneath a translucent sheet of glass.

Plot hooks
1A rival scholar steals the glass-sealed page, believing it contains a usable ninth-level spell. The page is only theory, but the rival's experiments are causing people to lose their voices.
2The codex's brass clasp bears the crest of an abandoned observatory, where its original owner hid research into a death-word and a countermeasure against it.
3One silver annotation has begun rewriting itself in a hand that matches no known scholar's. It names a location and a date that have not yet come to pass.
