Forgemaster

The Forgemaster was one of the members of the Regency Council of the Dwarf Kingdom, until he fled the Kingdom after he stole a piece of metal ingot from the Sorcerer King.

The Craftsman of Dwarf Arc
The Forgemaster is the only councilor that was adamant in rejecting the offer of assistance from the Sorcerer King. He utterly refused to accept Ainz's aid in exchange for the runesmiths, but he was outvoted by the Regency Council. Later, he was asked by Ainz to construct a set of armor for a gift he wished to present to one of his subjects. The Forgemaster was given an ingot of a peculiar metal that the armor was to be made out of.

However, after a day of failing to heat the ingot the Forgemaster gave up and disappeared with the ingot in tow.

Abilities
As the Forgemaster is renowned as a genius in the art of blacksmithing.

Ainz Ooal Gown
The Forgemaster detested the Overlord, seeing him as a tyrant that had come to enslave his people. His hatred of Ainz furthered when he was given the task by the Sorcerer King to construct an armor with a metal he had never seen before. It tortured him in his inability to even heat the ingot of metal, caused him to be humiliated and lose his pride as being hailed a genius in black-smiting.
