Andrivete and her older sister Guinevere have found themselves on opposing sides of the conflict growing between Camelot and the Isles. After having survived the assassination attempts at their witchcraft trials, both women are now being fiercely protected by their kings. Morgana continues to play dangerous games exacerbating the growing rifts between King Arthur's knights while falling victim to a knight of her own in the Isles. Dark shadows have overtaken Camelot, and while Andrivete tries to get Guinevere out of the kingdom, it's clear, Guinevere has a plan of her own. New truths prove unsettling at Andrivete's dreaded 25th birthday celebration. Merlin makes one final shocking sacrifice with his power for Arthur, and fighting has now come to the killing fields of Camlan. It's anyone's guess who's going to survive this final onslaught, but the survival rate doesn't look good. Will any of the witches be left standing when the smoke clears, or will Andrivete and Rience be denied their happy ending?
