The Guardians must face an ancient enemy – Dark Mother. She was once Meter the Queen of Spring and made flowers bloom beneath her feet. But when she became corrupted, she transform into Dark Mother and attacked Kandrakar. She was defeated by the Elemental Queens of fire, Water, and Air and was casted into the dark void where she continued to wait patiently in chained. In silence, Dark Mother sent a seed and planted it in Kandrakar where it will served as her infiltrator against the Fortress of Light. The Guardians received their New Powers, making them stronger and giving them new abilities and new outfits. Matt now served as their new trainer and mentor after being recruited by the Oracle to prepare them for their upcoming battle against Dark Mother. One by one, The Guardians found the root of their elements and obtained control over their new powers. Meanwhile, Dark Mother escaped (thanks to Will) and set off to take over Kandrakar. Thanks to her tree which she had planted beforehand, Dark Mother enslaved the minds of Kandrakar, except for Yan Lin. The Guardians later faced her in one last battle and Dark Mother was sealed in a stone tomb. Oracle Himerish relinquished his place to Yan Lin who foresaw the coming threat and left without saying good-bye.
