Samwell is a steward in the Night’s Watch. He is intelligent, well-educated, and insightful, but overweight, unskilled at combat, and believes himself a useless coward (though at least HE openly admits he is a coward and occasionally shows stirring moments of bravery) In spite of his exterior, he is one of only a few humans who have survived an encounter with the White Walkers, and perhaps the first human to kill one in thousands of years.
