Tol was one of a number of Ferengi hired by former DaiMon Bok in 2370 to assist him in resequencing the DNA of Jason Vigo to make it appear he was the son of Jean-Luc Picard. Tol and the others believed Bok's intention was to hold Vigo for ransom, but later learned Bok intended to kill Vigo to exact revenge for the death of his own son at the Battle of Maxia in 2355. Upon learning this, Tol and the others turned against Bok. (TNG: "Bloodlines")
