Arthonen was a Dunedain Ranger of the North whose village was attacked when he was still young. When he was close to twenty years old, the Angmarians attacked his village and captured his betrothed and took her away. Little did he know that she was sold into slavery to an Orc named Kargin. Arthonen stayed in his village to help repair things and then set out at the age of twenty-five to find Miluiel. Still at eighty-seven years old he continued to search and met with Xantalin Redsword. Together they guarded the very passage of the Misty Mountains that Skargim and his friends took. They joined Skargim and together they saved the Lonely Mountain and Arthonen found Miluiel and they Lived long and in peace for some time.
