The opening
A museum asks the characters to recover cuneiform tablets stolen from a storage room. Their consultant, Ashur, says the thieves are joining broken fragments from Ashurbanipal's library and selling the completed texts. When the first tablet is restored, a modern border gate hundreds of miles away closes by itself.
Ashur reads the tablets without notes and treats royal commands as personal insults. He leads the party beneath Nineveh, where fire hardened thousands of records instead of destroying them. Every complete sentence changes something outside.
What the party is trying to do
Recover the stolen tablets and stop the library from enforcing ancient commands in the present.
A route through the campaign
- Track a collector who used an omen tablet to make every prediction in his favor come true.
- Enter a burned archive where spoken words pull matching fragments through the rubble.
- Find Ashur's face carved beside the royal catalog and watch him deny the resemblance.
- Choose which medical and literary tablets to save before the command texts awaken the palace guard.
- Reach the throne archive as Ashur names himself Ashurbanipal and orders the library to classify the party as enemies.
Possible endings
- Defeat Ashurbanipal and distribute the surviving texts to the cultures they came from.
- Destroy the command tablets while preserving medicine, literature, and records.
- Rewrite the catalog so no single version of a law can rule every place.
History and invention
More than 30,000 cuneiform tablets and fragments were found at Nineveh in collections associated with Ashurbanipal. They include literature, omens, medicine, ritual, administration, and intelligence. Fire hardened many clay tablets. The magical authority of rejoined texts is an invention.
Content notes: war and conquest, cultural theft, destruction of archives.
