A sturdy steel sword forged by the method of folding.
It has a dull shine with a cold glimmer.
It belonged to a famous adventurer who witnessed the vastness of the earth.
With it, he severed the iron bones of monsters and crossed blades with bandits.
But in the end,
He gave up the vast earth, the boundless sky,
His friends in the Guild, his trusty Cool Steel, and old pals, to be with the girl he loved.




  • The adventurer whom the description references is Herman. He can be found in-game in Mondstadt wandering near the path towards the Cathedral. If you speak to him, he will mention that he is worried because he will not have enough Mora to buy a sword as a birthday gift for his daughter, Ellin, since she wants to join the Knights of Favonius. When he retired, he forced himself to sell the sword.
  • If you speak to the weaponsmith Orban, he mentions that he forged this weapon for Herman. While the sword is famed, he doesn't consider it very special amongst his works, instead he wishes to make a truly legendary weapon.
  • Kaeya is seen wielding this sword in his official Character Demo.
