Around 2022/2023 Penguin re-released 40 new audiobook version of the Discworld stories.
The announcement makes it fairly clear that each sub-series, Witches, Guards, Wizards etc, has a dedicated narrator and that the voice of Death and The Footnotes is consistent across the whole series.
...with Bill Nighy as the voice of the footnotes, and Peter Serafinowicz as the voice of Death.
Some of the individual book pages though list more than 3 readers. Carpe Jugulum and Guards! Guards!. But these additional readers don't seem to follow through into other books either within the sub-series or elsewhere.
Do any additional voice actors provide the voice of single specific characters across multiple volumes of the audiobook series?
