The dwarf race has long been known as one of the pioneers of architectural experts.
Arthur's relationship with several dwarf races was formed while he was actively involved in the underground black industry.
Arthur's journey as a novice Atelier and the curse of his Netori System has led him to form a cooperation contract with a dwarf named Darinci.
Darinci is one of the dwarves who has been exiled from his group because he was involved in a suspicious business involving illegal activities such as making a basement for a noble family's sex slave residence, making anti-magic houses for the rich, and making several other illegal buildings with a large amount of payment.
The involvement between Arthur and Darinci began with Arthur's cunning scheme to take a first-class Atelier license involving sabotage and hijacking a large library that stores several forbidden Alchemist books that cannot be displayed in public spaces.
