These posters are tacked all around upper sanctuary, a copy is also attached to the door of the Mushroom's ruin.

Attention,

I seek information considering the possible survivors of the Sslal'teesh assault on the Blue Mushroom inn. If you hold any knowledge of the said deep gnomes, leave a note for Krestorrin at the Pissing Crone.

I was once told there was a possibilty some of the gnomes were kidnapped and taken back to the Moander temple. This was a long time ago and I can't garuntee this information is true. But it might be worth checking out.
