Pearl

For eons, the Bubble Magi were the greatest defense the Legion had against the Beasts and Demons. Their protective magic circled the Legion cities in domes that kept the enemy assaults at bay. When Maliken betrayed the Legion, his agents simultaneously assassinated every Bubble Mage known to the Legion and burned their monasteries to the ground. All of them... save for one lone apprentice who was mistaken for a mere servant and one pet turtle who had watched his master from afar. Searching among the ruins of her home, she discovered her master's staff still clutched in his charred hands. As she took up his weapon, she finally allowed her tears to flow and her determination became clear. She has spent years honing her craft and now Pearl, the last known Bubble Mage, has taken to the battlefields to bring vengeance down upon Maliken and his demon horde.
