Now by Acting I do not mean that the players can necessarily defeat it at 1st level, just that they can have some sort of interaction with it. They could:
- Try to find out who put up the posters or paid for the announcements. (a patriotic citizen, or a fifth column).
- Talk with the Sultry Bard and hear her lies.
- Bargain with the merchant.
- Deal with suspicious town guards.
- Discover the Sultry Bards' lies.
- Visit Country A and discover identical posters, the same merchant and the same Sultry bard.
If the PC's cannot interact with what they observe, then don't bother showing them.
