Ashtone Martin is the Forging master at the Royal Academy, as well as the mentor to Xiang Ye. He is treated with great respect by the other teachers despite the fact he does not have any boundary force. As revealed in chapter 34, he invented the forging class, all by himself, by working with the Dwarf miners, and watching them work, he diligently labored to adapt their use of "Gold Alloy Crystal" into its current form, safe for human use. He also made the walls to The Capital.
He is a kind man who cares deeply for his students. Slow to anger, he treats most with respect. He's a firm believer in the Regan Era doctrine "peace through strength," which he learned from the Dwarf tribe. He never stops singing Xiang Ye's praises, happily proclaiming that Xiang Ye's not only his best student, ever, but will one day, soon, easily surpass him, at his prime. He even gifted him with The Pale Moon Stone
Aside from his mustache and eyebrows, there is not a hair on his head. (as a result of creating the capital's walls) He is fairly tall with a muscular build and is always seen wearing the same purple robe.
