Old Longfellow is a septuagenarian hunter and bodyguard living out of a cabin near Far Harbor in 2287. He is a possible companion to the Sole Survivor.

A native of Mount Desert island, Longfellow is old enough to remember the days when the radioactive fog covered almost the entire island. His indomitable will and fit physical structure still manage to keep up with his old age.

Old Longfellow is a seasoned hunter who can recall a fairly large portion of the region's history; from desperate struggle to prosperous hubris. Longfellow is a veritable legend in Far Harbor circles and one of the few guides capable of guiding a person safely through the fog. His age and experiences made him cynical and he hits the bottle of whiskey a bit too often in recent years.

Longfellow deeply loathes the Children of Atom. When he was a young man, he was in a romantic relationship with a girl named Hannah and the two had planned a future together. The cult's followers attacked the pair at their hideaway deep within the fog and abducted Hannah. Left for dead, Longfellow eventually made it to civilization. It took the hunter two months to recover from his injuries and by then it was too late for Hannah. Atom's zealots had warped her mind and turned Hannah to their ways. The child she carried was stillborn, due to the radiation she was exposed to and claimed it was "Atom's will" for it to have happened. Hannah afterwards fell victim to the insane trappers that roam the island. Longfellow became an embittered shell of a man, mostly regretting the death of his child.
