Summary
Thistle, known as Sissel in the Yen Press English translation but retaining the name Thistle in the official Japanese manga, is a mage over a millennium old with a birthday on February 21 and a birthplace in the Northern Central Continent. Standing at 130cm with a BMI of 17, he is the architect of the dungeon on The Island and serves as its lord, wielding immense authority over its structure and the monsters within. His lifespan has been prolonged by the dungeon's power, allowing him to reshape the environment at will, frequently opening holes in the ground to eliminate foes or facilitate his own escape. He commands monsters to his aid, such as instructing the Red Dragon to locate King Delgal, and relies on small dragons called 'the magician's eyes' to monitor changes within the dungeon. Thistle is depicted as irrational and resistant to reasonable dialogue, displaying a single-minded devotion to King Delgal and the Golden Country. When frustrated, he engages in self-harm, often scratching his head until it bleeds or chewing on the tip of his thumb.
