Magi: The Labyrinth of Magic, Vol. 19

Summary

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.
Magomett, the leader of Magnoshutatt, learns that the Kou Empire plans to attack while the city is weak from fighting against Leam. In desperation, he uses the Magoi Reactor to create a terrifying blackness in the sky. The very essence of the world is now threatened and Aladdin must summon his most powerful allies to try to stop it!
