Magi, Vol. 20: The Labyrinth of Magic

Deep within the desert lie the mysterious Dungeons, vast stores of riches there for the taking by anyone lucky enough to find them and brave enough to venture into the depths from where few have ever returned. Plucky young adventurer Aladdin means to find the Dungeons and their riches, but Aladdin may be just as mysterious as the treasures he seeks.
The battle for Magnoshutatt reaches its devastating climax as the terrible Dark God takes shape and powerful Metal Vessel users from across the world arrive to join the battle. Defeating the Dark God will require Aladdin and Yamraiha to confront Mogamett and uncover his secret. They may also find the sacrifice required for victory too much to bear.
