What is Merlin's sign?

Merlin's sign refers to the astrological sign associated with the legendary wizard Merlin from Arthurian legend. While there is no definitive astrological sign attributed to him, he is often depicted as a wise, mystical figure, which could align with signs like Pisces or Aquarius, known for their depth of intuition and connection to the mystical. Ultimately, interpretations may vary since Merlin is a fictional character rather than a historical figure with a specific birthdate.
