Illustrated Guide to the world of Spira (FFX and FFX-2)/Hidden Dungeons
There are 14 dungeons in the world of FFX and FFX2. Dungeons in Spira vary very little in style, most of them look like ancient stone temples with a hint of Ancient Egyptian stonework. Notable exceptions are Bevelle Cloister, Bevelle's underwater maze and the cave dungeons on Omega Ruins and the Den of Woe. Mt. Gagazet has a very unique cave dungeon with some parts submerged under water.
