Iron Horse was for three generations a Tlingit tribal medicine man. He died in 1803, at the Battle Creek Cayahote. The Watchers knew little about the Tlingit, but in 1883 he was watched by a tribesman named Elk Moon.
Iron Horse finally lost his head to a U.S. cavalry officer, Captain James Darling, when he and his soldiers massacred Iron Horse's village. Both Elk Moon and Darling's Watcher were killed, so that the actual events are still unknown. The Watchers, however, recorded the death of Iron Horse. In their archives they have the pipe of the medicine man, burned by the energies of his Quickening.
