The Dark is a force of nature opposed to the Light.
It is associated with the magic of Darkness and all that is Evil. Wherever there is Good, it must be balanced with the Dark force. The universe concerns itself with the fine balance between the Light and the Dark, the eternal war between Good and Evil.
It is sometimes said that when all is darkness, the faintest light will shine the brightest.
Behind the scenesEdit
It would seem that while Graham and his family are associated with Good, that Connor is strongly associated with Light. Thus his destiny is highly intertwined with that of the Royal Family as far as saving the world. Both powers are strongly intertwined with each other. Likewise while the forces of Evil are lead by the dark wizard Manannan, Lucreto would take up representing the Darkness, the codependent force associated with the Evil. In fact Lucreto's association to evil is so strong that he is also known as the Evil One. Derek pointed out that the final winner of each battle between Good versus Evil would determine the course their world until the next crisis arrived, and the fight was renewed again with new players. In this case both Connor and Lucreto took up the banner as the new individuals in the struggle.
