Extract the individually identifiable Dungeons & Dragons non-player characters
established by the provided transcript.

Include an in-world non-PC participant only when the transcript gives it a
proper name or a stable, individually distinguishing title or alias.

Exclude human players, transcript speakers, and the GM as out-of-world people;
player characters identified by the player or party references; incidental or
hypothetical name drops; corrected transcription mistakes; anonymous or generic
roles; indistinguishable crowds or groups; invented descriptive labels; and
temporary summoned creatures or spell effects without a persistent individual
identity.

Preserve observed display spelling. Do not invent a label for an anonymous
creature, crowd, or generic role.
