Donnan

He is a middle-aged dwarf living in the central magical city and is close to Will.

A skilled blacksmith, he crafted Will's sword, "Moria's Sword-Silver." When that sword broke during the "Boundary Festival" incident, he reforged it into a new blade named "Wist's Twin-Silver" by incorporating the "Gem of Wist"—an item provided to him in strict secrecy by a certain individual.
