Im: Great Priest Imhotep Vol. 10 (manga)

In a shocking betrayal, Khonsu has stolen Djoser's mummy--with none other than Apophis pulling his strings. Using the mummy, Apophis plans to make a complete revival, gaining even more power in the process than he possessed during the Age of the Gods. It's up to Im and all his allies to stop the evil god's plot--but first, they'll somehow have to force their way into the mythical Primordial Hill!
