The designation of Master Trail Guide was bestowed upon Wookiees who demonstrated complete proficiency in navigating the diverse routes of the Rryatt Trail located on Kashyyyk. The responsibility of these master trail guides involved escorting travelers along the trail, leading them securely through the different levels and pathways to ensure their well-being and safe arrival.
During the year 1 ABY, the individual holding the position of Master Trail Guide was a male Wookiee known as Achonnko.
