Longshanks

The Longshanks are hardy outdoorsmen that fill the same niche as templars in other cults. They vow to never remain in one place for longer than a week at a time, and wander the thick woods of the Empire ensuring that the shrines, temples, and glens dedicated to Taal and Rhya are in good repair and working order. They bring swift death and retribution to anyone they find desecrating these sacred places. Longshanks protect pilgrims making their holy rounds from the predations of Mutants, Greenskins, bandits, and other threats. When the Storm of Chaos swept through the Empire, the Longshanks served the Emperor as outriders, scouts, and raiders.
