"Drinking at the Singing Mandrake leads to rumours about who the Rosers were and where they went. There is disagreement about where they found their roses: dreams, mirrors, a trick, a gambit, a seduction."[1]
The Rosers were a group of Revolutionaries from the Fourth City.[1] They took refuge from the Masters in Arbor. Their exact location has been a mystery since London fell, but they are believed to reside in Parabola.[2]
