Together with Haldir and his other brother Orophin, Rumil is one of the few Lorien Elves that every once in a while venture outside of Lothlorien to gain news of the outside world. He also knows a little bit of the western tongue, but we never hear him speak.
In the book he escorts the Fellowship along with Haldir further into Lothlorien untill they reach it's core. He stays on the other shore as the Fellowship crosses the river.
We must not mistake Rumil of Lorien with the Rumil mentioned in The Silmarillion, for this Rumil was a Noldorian Wise who was the designer of the first written markings.
