Cut the onion, carrot, celeriac, potato, fennel, turnip, and artichokes into medium to large chunks. Heat the olive oil in a large soup pot. Add the onion and cook until softened but not browned, about 5 minutes. Add the carrot, and cook for 5 minutes, and then add the remaining vegetables at 5 minute intervals, adjusting the heat as necessary so the vegetables don't brown. When all the vegetables are soft, add the chicken stock. Bring to a boil, reduce the heat, and simmer for 5 to 10 minutes, or until the soup has come together; it should have a thick consistency. Garnish each bowl with the chile powder and more olive oil.
