Anzu took the three other elementals back to his hideout. He had found a ritual in an old spell book years ago that could combine all four elementals' powers into one person. Anzu knew he wouldn't have a lot of time before the Fairy Tail wizards would find him, so he had to act quickly. He entered the dungeon of his fortress and quickly chained the three Fairy Tail wizards to the cold, stone wall with anti-magic chains. As the ritual progressed, all that could be heard were deafening and painful screams as Anzu drained every last drop of magic energy that he could from the three young elementals. They were completely helpless against Anzu, and they could only hope that the torture would end soon. It took a total of three excruciating hours before their magic was completely gone. Once the ritual was over, Anzu tried his new powers by summoning flames, controlling the air at will, and moving huge boulders within the dungeon.
"Hahaha their magic is finally mine! Nothing can stop me now that I have the power of all the elements!" Anzu laughed as he left the room, leaving the three powerless teens extremely weak and exhausted. About an hour later, the door to the dungeon was smashed to pieces. Once the door was out of the way, everyone - Eve, Hibiki, Erza with team Natsu and even Laxus - stormed in. When they saw the horrible condition the three were in they immediately rushed over to untie them; obviously Eve went to Aria, Hibiki went to Zola and Erza went to Kai. The elementals - or ex-elementals - ended up collapsing right after the bindings were removed.
"What're you guys doing here?" Zola asked tiredly, but too stubborn to succumb to her exhaustion.
"We came here to save you guys, obviously." Natsu answered matter-of-factly.
"Yeah, we weren't just going to leave you guys. You're all a part of Fairy Tail, and we never leave our own behind." Erza assured.
"We need to get out of here. That guy may come back if we don't hurry." Laxus said as he kept watch right outside the doorway. Eve and Hibiki both picked up Aria and Zola bridal-style, and Erza hoisted Kai onto her back. They quickly escaped the dungeon and made their way back to the Fairy Tail guildhall, fearing the worst for Aria, Zola, and Kai.
