Redeemer

Redeemer is a longsword forged from Shimmering Steel, its blade adorned with intricate motifs of a dragon's head. The hilt is wrapped in red leather, providing a secure grip, and the pommel is set with a ruby that seems to glow faintly. The blade itself reflects light like a blazing fire, and it hums softly when drawn, as if resonating with the power of dragons.

Redeemer's legendary status, powerful enchantments, and unique connection to dragons contribute to its high value. 

Itis the ancestral heirloom of the Dragoon family, a noble house renowned for taking part in the Grail War. The sword was forged for the purpose of punishing the wicked. The Dragoon family wielded this longsword in their battles, commanding the power of fire to aid them. However, Redeemer was lost after the Grail War, a conflict that saw the Dragoon family fall from grace. Legends say that the spirits of the Gylder River now guard the sword, waiting for a worthy wielder to reclaim it.
