Mnemonic

The prefecture Suspends a lineage scroll from its ceiling. It dangles right over the heart of the main hall, swaying like an unresolved question—a family tree no one dares to claim, hanging heavy over every heart that passes beneath.
Additional thoughts
Picture a giant ancestry scroll physically dangling from the rafters of a government building. The prefecture put it up as a bounty—whoever proves their lineage claims the reward. Its placement over the heart of the hall makes it an emotional, nagging concern for everyone who walks under it.
