Magic Craftsman

Magic Craftsman (魔法工) was a member of the Thirteen Heroes and Runesmith King of the Dwarf Kingdom in the Azerlisia Mountains.

Appearance
Magic Craftsman was a dwarf hero, who wore a shining metal armor.

Personality
Little is known of the Runesmith King's personality, but it can be surmised that Magic Craftsman was quite vengeful, as he broke the traditional isolationist policy of his people to pursue the Evil Deities after they murdered his family.

Background
At the beginning of his heroic deeds, what is known about the Magic Craftsman is that he was a dwarf who slew a Dragon. He was the last surviving member of the dwarven royal family and would band with other powerful individuals, who came together and formed the renowned Thirteen Heroes to fight against the Evil Deities. His memory would live on through his subjects, who would recount his heroic deeds in their feast halls.

The Lizard Man Heroes Arc
When six thousand Nazarick Old Guarders appeared at the foot of the Lizardmen Alliance village, Zaryusu marveled at their magical equipment declaring that not even the famous dwarven artificer could craft that many weapons in such numbers.

The Craftsman of Dwarf Arc
A lot of details regarding his exploits and deeds as well of his families lineage were mentioned and explained by Gondo Firebeard to Ainz when talking about the history of the Dwarven Nation as well as his abilities in Runecraft, magic items and his national treasures.

Abilities and Powers
Magic Craftsman was praised as a worthy metal-smith and that he had defeated a dragon in single combat. It's noted that the Runesmith King took all the dwarven national treasures in his kingdom when he set out to battle the Evil Deities. Even within the legends told by the dwarves, there were no stories which told of this kind of magnitude of magic equipment preparation — for a legion exceeding over five thousand units.

Main Equipment

 * Magic Warhammer: A national treasure, crafted by Gondo Firebeard's grandfather. It was carved with six runes and had the power to cause earthquakes. The weapon was viewed as a secret treasure of the runesmith’s art.

Trivia

 * Magic Craftsman's departure from his kingdom, ended the long period of isolation in the Dwarf Kingdom.
 * It is hinted that since Magic Craftsman nor his treasures ever returned to the Dwarf Kingdom, he may have died somewhere along the journey in fighting the Evil Deities.
