Working on my comic book

Whisper of the Dragon is a sword forged from the same steel as Excalibur. It was created by blacksmiths monks from the Kingdom of Toledo, they used a secret method for hardening the blade. In the begining it had the color of steel, but after so many wars, the blade had lost its shine. Washed in the blood of his enemies, the sword of Vlad the Impaler became red as a ruby.
