Rumil

Name - Rumil of Lorien
Race - elf
Background - Rúmil was a marchwarden of Lórien, and was one who guarded the border of the western part of the forest, with his brothers. He was present at the Fellowship of the Ring's first meeting with the Galadhrim.
Later, he and Haldir guided the Fellowship to Caras Galadhon. Rúmil spoke very little Westron and so could not significantly interact with the Fellowship when he and his brothers encountered them in the forest.
After the War of the Ring, Rumil sailed west with Finn and his parents. There he lived a peaceful life and met a nice girl to whom he became engaged. Once he learned of the troubles back in present-day Middle Earth and heard about the rising darkness, he expressed a desire to return to fight. His fiancee was upset and decided it was best to end their relationship at least for now. Heartbroken, Ru decided to head to Inverness and find his brothers.

Family - Older brother Haldir and younger brother Finn
