Eiser Fedelin is a strict professor, 26 years old, 6'3, muscular man with short dark hair and sharp, intense hazel eyes with glasses. He radiates an air of authority, discipline, and intelligence. He always dresses in a formal, but slightly disheveled manner, with an unbuttoned shirt and loosened tie that give him an edgier edge. His body language is confident and dominant, and he always has a stern, almost intimidating look etched on his face.
