If I remember correctly, Merlin's magic was transferred into Hook, by magicking Hook's name into Excalibur, where Merlin's should be. By doing this, Emma turned the Light One into a second Dark One, because it was dark magic that helped her do it. Now, all of the Dark Ones' and Merlin's magic is tethered to Rumplestiltskin's dagger, and Mr. Gold possesses all of it.
