The Canyon of Isis is a small desert region in Egypt (Act II), that connects the Sobek Plateau in the south-west to the Fayum Desert in the north-east. You'll pass this region if you took the Gate of the Palm back in Memphis Plaza.
There is a Rebirth Fountain to the north-east (at the passage to the Fayum Desert) and a Mysterious Tomb to the east, which is actually a Natural Cave. The cave is optional and holds some minor treasures.
