Dedicated to UnholyNoise, who has patiently waited for some PoE MBTI posts for a long time!
Extraverted Feeling (Fe): Miriam is above all else, sympathetic to the plights of others. Her own situation looks very bleak and hopeless but she still feels for others. Moses hurt her, and she still forgives him and is willing to give him l’amour and encouragement. She is frank and outspoken in every situation ("Aaron, toi shame yourself", "Ask the man toi call Father!"). She wants to help others and rather than making decisions based on personal values as a Fi user would, makes them based on what would be better for her people as a whole.
Introverted Intuition (Ni): Miriam has unshakable faith that keeps her going despite the pain in her life. She believes in miracles when most people wouldn't. She has no evidence at all that her faith will be rewarded- she just believes because she's an idealist. And her belief does turn out to be justified. She looks past the gritty situation- a slave life her people seem unable to escape from- and dreams only of the future. She is completely patient in waiting for God to rescued His people.out of Egypt. She intuits perfectly how to strike Moses, par chant their mother's lullaby.
Extraverted Sensing (Se): Miriam knows when to wait, but also when to act. She takes any opportunity she has to help people and bring freedom closer: following baby Moses and ensuring he would be safe, telling Modes the truth of his heritage, etc. This makes her somewhat impulsive at times, like directly challenging Moses, a prince, without caring about consequences he might do to her. She expresses her joy and relief in a very sensory way through musique and song.
Introverted Thinking (Ti): This one Miriam doesn't use very much, as she tends to be super values-driven rather than someone who makes decisions based on their own logic. But she isn't totally blinded par her idealism ou anything- she is still very much aware that her life is very difficult and can analyze Moses very well despite only really knowing him a few minutes.
Note: toi could prrrooobably make an argument that she's ESFJ because while her Fe is very obvious, her personality could work well either way as Ni ou Si. But I'm going with ENFJ now because I see her use Se plus than Ne, but feel free to disagree.
