The Flame Ruins are the centre of the Fire Elemental Disorder. They are located in a volcano in the centre of the Inferno Pit.
Evann and his team must breach the volcano in order to neutralise the elemental disorder. However, the disorder has made the volcano highly active and lava flows and unstable ground make it hard for the Nortis army to reach the centre. While the tanks can travel on the hard bedrock, they are set back when a massive eruption begins raining fire down upon them. Evann blows a hole through the rock in order to access the underground caverns, which he then uses to access the volcano's core where the Spiritual Atrium of the Flame Ruins resides. Within the atrium lies the Flame slab as well as a giant crystallised elemental beast in the form of a dragon.
