Proteus

Proteus was the name of a steam engine in an old story from the hills. Proteus had a lamp that shone very brightly and was said to be magical. There are three signs that Proteus' lamp is near: a gust of wind, a creaking sound, and a light flashing on and off.

Skarloey once spoke of this legend to the other narrow gauge engines. Peter Sam scoffed at the story at first. Later that evening, when Peter Sam got lost on an evening voyage, he was almost led to believe that the lamp was about. In the end, Peter Sam decided that sometimes it can be good to believe in something. ("The Magic Lamp")
