A signal station, also referred to as a signal tower, was a tower-shaped construction designed to hold fireglobes at its highest point. An individual could use these glowing objects to send visual communications from one signal station to another by means of a language called semaphore. The Signal Corps, a division of the militarized government of Alanciar, a continent located on the planet Kesh, operated these signal stations within their civilization, maintaining vigilance against a potential invasion by the Lost Tribe of Sith, who resided on the western continent of Keshtah.
