A collection of 30 bardic tales you may hear sung in the local tavern or empresses' court, complete with bardic verse excerpts from all 30 tales themselves.
Many of these tales can also be used as quick plug in adventures for Gm's looking for a side quest. (And let the players exploits be turned into the song by a near by bard perhaps?)
A noble claims that a stranger did not enter the town by any normal means, but trough his mirror. The man in question is ravening mad and mutters on about vast halls connecting all the mirrors in the world.
