Mount Gulg

Mount Gulg, also formatted Mt. Gulg,  is a volcano and one of the dungeons featured in Final Fantasy. It is found on an island, at the end of a maze of rivers flowing north from Crescent Lake. At first, Mount Gulg can only be reached by canoe, but later, once they gain the airship, can land it on the island. The boss of Mount Gulg is the Fiend of Fire, Marilith. In the Nintendo Entertainment System release, the place is known as Gurgu Volcano.

History
In Final Fantasy, Mount Gulg starts as a dormant volcano, but after the Warriors of Light defeat Lich, Mount Gulg begins to erupt. As the warriors travel through Mount Gulg, they find Marilith at the end. She is found at the Altar of Fire, draining the power of the Fire Crystal, and thus causing the volcano to erupt and fires to occur around the world. Once the Warriors of Light defeat Marilith, the Fire Crystal's power is restored, and the volcano becomes dormant again.
