Sword of the Fiery God: Yfaestus!!

"Should you face a man with this at hands, you'd surely burn till the bones. Made of Lesser Red Dragon's bones and imbued with the flames of the Ourobouros itself, the dragon's malicious god, this sword has it's name as a tribute to greek's ancient god  Hephaestus, as only the ugly blacksmith god of fire and volcanoes could forge such rustic yet elegant sword, powerful as only the gods has ever seem weapons to be. It is actually unknown who made such neat destruction tool, but the heat it's blade produces is about 25 000 Kelvin, just like Zeus's thunderbolt, that happens to be forged by Hephaestus."
