The werelynx is wise.........bards are good; another bard module would be very good. Not that I have any crazy preference, or anything.

Seriously, though, I
would love to see another bard-centered module. By the way, since bards are great for multiclassing many different characters might qualify, should you not require a pure bard character. For example, if the Perform skill were needed, any character with a good amount of Perform (via skilldumping, perhaps) could succeed; I think there are quite a few possibilities.
