Dwarven Music Box Blueprint
From Will of the Seven Campaign
Dwarven Music Box Blueprint is a copy of a schematic for what appears to be a clockwork musical instrument. The document is written in Dwarven language, and incomplete, but a skilled tinkerer can, through trial and error use it to re-create a device approximating the original Dwarven Music Box given enough time.
The document was found by Bilbido Tastyflute inside Lord Aiden's Trade Ledger while exploring Lord Aiden's Mansion.
