Legend has it, the Flame Demon Gross was originally the ruler of the Molten Lava Crown on the Dragon Sleep Continent.
Later, a Black Iron Dwarf Tribe named Copper Furnace migrated to the Molten Lava Crown to escape the Abyss. Realizing there were abundant geothermal resources underground, they decided to settle there.
From that day, the Copper Furnace Black Iron Tribe and the Flame Demon Gross began a prolonged ten-year struggle.
The struggle between the Copper Furnace Black Iron Tribe and the Flame Demon Gross went on for too long. Many times, the Copper Furnace Tribe considered giving up and seeking another habitat.
Until a Black Iron Dwarf King named Sorondar Copper Furnace emerged, leading the Black Iron Dwarves to defeat the Flame Demon Gross and secure the victory.
After the Flame Demon Gross died, its ashes scattered beneath the Molten Lava Crown, seeking an opportunity to revive.
