Surmissieth is cold, calculating, and emotionally distant, shaped by the trauma of losing his mother and witnessing his father's descent into madness. He suppresses his emotions, believing they lead to weakness, and holds a deep mistrust of humans. Despite his ruthless exterior, he carries the heavy burden of leadership with a strong sense of duty. Though outwardly detached, he harbors a quiet sadness and refuses to let himself feel love, seeing it as a dangerous vulnerability.
