Found scrawled on walls throughout Kirkwall:

For the best penetration in Kirkwall, see Isabela at the Hanged Man

Drawn under that surprisingly literate line is a stick figure of a man with one dagger in his eye and another in his crotch.

Mages do it magically.

Found twenty feet up the outer wall of the Gallows in four foot tall letters: Meredith is frigid, but Orsino's got a fire spell for that

Carved into the privy wall in the Hanged Man:

A charming and erudite feller
Just because he ain't tall
Don't think that he's small
He plumbed me so deep he found my root cellar

Under that: You swore you'd never tell Isabela
