The Brass Sextant (Sextante de Latón) first appears in Volume 2 as a mundane maritime navigation instrument, but its significance grows as it becomes tied to the mystical forces of the seas and the pathways of the Sailor and Mystery Pryer sequences. Across the series, it evolves from a simple tool into a symbolic and functional artifact that aids in navigation through both physical and metaphysical waters, reflecting the series' themes of hidden knowledge and the dangers of the unknown. Its recurring presence underscores the tension between the rational world of science and the supernatural mysteries that permeate the Lord of Mysteries universe.
