1002 Demon Overlord

Unfortunately, one day, while excavating a vein of ore, a Beastman Tribe accidentally released a Greater Demon Overlord that had been suppressed in the Black Burn Scar.

That Greater Demon Overlord destroyed that Beastman Tribe the instant he was released, and the entire Black Burn Scar, the most fertile mining area of the Raging Flame Plane, was also destroyed. All the ore veins and precious resources had been thoroughly destroyed. From that point on, the Black Burn Scar became a land full of chaotic flames.

This legend was considered one of the most widely spread legends of the Raging Flame Plane. At the time, Sky City occupied an area close to the Black Burn Scar, and they naturally focused on exploring that place, yet they didn't gain anything.

Raphael was one of those people that entered Black Burn Scar, so he could see that this place was an exact replica of the Black Burn Scar.
