The Lava Caves are a network of volcanic passages located on Alfard. The caves are accessed through Azha Village. The mining of Flame Ice acts as a major livlihood for the people of Azha as well as a target for abuse by Alfard's government. One of the five End Magnus are located within these. The caves are inhabited by various fire monsters as well as the Lord of the Lava Caves.
The caves serve as the location where the final End Magnus is unsealed, and Geldoblame's intentions are revealed.
