“The volcano's guardian puts on quite a show.”
The Phoenix Mountain is the location of the fake Wish Seed. It is guarded by the Phoenix which has been angered by Underworld forces in Chapter 10. Pit must make his way through pools of lava, caves and many Underworld forces. The extreme heat and endless lava make it impossible for human life to survive on this mountain, but Pit is able to survive thanks to Palutena's Power of Cooling.
