|Also known as:|| Master of Alchemy|
|Card:||The Hermit, Master of Alchemy|
|Family:||Unnamed Father †|
Arthur was the Hermit Arcana known as the Master of Alchemy. He was killed by Evie.
He murdered his father by dissolving him with acid.
Arthur sets up his home with strong windows and an unopenable door, and lures people inside. After this, he drugs them and makes them tell their story about what they did after The Flash, then does experiments on them with his chemicals. He tries this on Evie, who recognizes the drug and manages to pour it out. Evie then creates vines and rips him in half after he attacks her with acid.
