Galt is usually described as sunken-eyed, cold distant person. Because of the modifications done to him by the Abolethic Sovereignty, his body is able to morph.
Personality
Because of a strong mental conditioning, Galt is an introverted person, usually lost in thought and mumbling to himself. He is able to show an astonishing concentration capacity when he had to focus in something, however, and he always takes his work seriously.
He is aware that Neverember only considers him a lackey but he doesn't care, as he is a faithful servant of his true masters. When commanded to do so by the aboleths, or when his life is in danger, Galt can turn very aggressive and only care for destruction.
Activities
As mayor of Neverwinter, Galt is in charge of the day-to-day ruling of Neverwinter.
He is also a puppet of the Abolethic Sovereignty, and his role is to inform his masters of any event of importance and to influence the government of Neverwinter in ways that would be beneficial for the aboleths.
