The class of characters that have not dedicated to any profession are called the Merchants. These characters will not advance as fast as other classes. They do not enjoy the pluses and bonuses as other classes.
New characters arrive in Drakkar as members of the merchant brotherhood. Merchants are welcome to explore the Kingdom, but after looking around, you'll want to chose a profession as a Fighter, Barbarian, Martial Artist, Mentalist, Healer, or Thief. When you decide which profession to pursue, you must find the appropriate trainer and dedicate your life to the pursuit of that profession.
