Legend holds that this blade was never forged by hammer and anvil. Instead, it was fashioned from the spine of the Fire Dragon King—the ancient ruler of the Volcano of Ten Thousand Eras.

Upon his death, the Dragon King's spirit and eternal flame fused with his own skeletal remains to birth this weapon. Wielding it grants the raw might of the Dragon King himself; every slash unleashes a torrent of incinerating fire that scorches all in its path. However, power comes with a price: the wielder must endure excruciating heat radiating from the hilt, searing their very flesh whenever the blade is drawn in battle.
