After returning home to Arcadia in the 21st century, and destroying the high school with Camelot's crash-landing, the team reunites with present-day Merlin, Toby, Blinky and AAARRRGGHH, and learn how Nari defected from the Arcane Order and sought protective asylum. However, the Arcane Order attacks and the Green Knight pushes the Onyx Shard closer into Jim Lake's chest. Jim sacrifices himself by pushing the shard completely into his chest, turning into a full troll and allowing him to fight back before he weakens. However, Troll Jim becomes enslaved by the Green Knight, who is revealed to be a resurrected Arthur Pendragon, now under the spell of Bellroc, the leader of the Arcane Order. The Order then takes the Amulet of Daylight and use it in a ritual to resurrect Morgana and re-induct her into their ranks. In the end tag, Arthur kills Merlin, and the wizard leaves behind a book for Claire and Douxie to safeguard.
