To put a new spin on an old phrase, hell hath no fury like a sorceress scorned.
So goes the tale of MERLIN, the international hit series that begins its fourth season on Syfy next Friday, January 6 with the first of a two-part episode that finds Morgana’s blinkered determination threatening not only Arthur’s future, but the very balance of the world. With her magic stronger than ever, the sorceress summons the mighty Callieach to tear open the veil between the worlds. Hellish creatures pour forth, killing any who succumb to their touch. With King Uther a shadow of his former self, it falls to Merlin, Arthur and his loyal Knights to protect the kingdom.
