Argantor's Helmet

Argantor's helmet, forged from a fragment of a fallen star, was the knight's main hope. The chronicles say that he withstood any blows, as if the will of Argantor intertwined with metal and made him invulnerable.
 
After the death of the knight, the helmet was placed in the tomb. But legends claim that Argantor's will was so imprinted on the metal that it granted him his own soul. When the kingdom is in trouble, the helmet miraculously appears on the altar, as if offering its protection.
 
They say that wearing it acquires not only invulnerability, but also the skill of an Argantor. However, the price is great: the will of the knight will subordinate the will of the bearer, striving for one goal — the salvation of the kingdom. But this is just a legend... Isn't that right?
