The Crimson Pilgrims is a legend perhaps related to the Sindar. During the Falenan Civil War, Killey mentioned the fabled group in a discussion with Zweig, who also researched the Sindar. After analyzing the details of Killey's story, Zweig believed that he had uncovered clues regarding the location of the home of the Crimson Pilgrims. Following the conclusion of the war, Zweig pursued his leads further, however, all he found was a single, towering tree.
