Sleeveless overcoats and five spiked headdresses are common among sentinels who guard the central mountain paths. They take pride in navigating steep elevation changes without any equipment or ropes aside from a multi-bladed halberd. Always watching at all hours, any weather, they maintain a constant number of sentinels per section of road recording activities. Their other function is to tease out the abilities of hostile forces. Giant traps, false assaults and fake encampments tempt invaders into revealing their tactics before the sentinels evaporate into cold mountain air.
