The three Breath Thieves are the Gnomic executioners.
The Breath Thieves wear red robes and hoods that cover all of them except their hands, even their faces. They sometimes appear as walking flames. When summoned, they carry a white candle in one hand and a long silvery tube in the other.
Three Breath Thieves, the executioners among the Gnomes, were summoned in Venom and Song when the Gnomes captured the Seven Elven Lords and put them on trial. Their silver blowpipes contained darts tipped with a poison deadly enough to fell a Gwar champion in three heartbeats. They did not appear again in the trilogy.
