In order to defeat the constant lure of Slaanesh, the Craftworld Eldar practice a form of deprivation, narrowing their focus onto a single craft, perfecting it and then moving on to another. However there are some who cannot stand such practices either through being unable to focus on one path at a time, having wonder lust for exploration, or simple dislike for the restrictions the Craftworld places on them. These Eldar then choose or are forced to walk the "path of the outcast", someone equipped to live off the land and to explore far and wide from the Craftworld. These are the Rangers. Many remain loyal to their Craftworlds even if they do not feel the need to live there, so when the Craftworld goes to war, they aid them with their experiences, offering enemy intel and their expert marksmanship to harry and cripple enemy forces and eliminate select target. Their preternatural skill finding the eye socket, neck joint or any other weak point on even the most heavily armoured enemy troops. While some never return home, either dead on some unknown world or consumed by their passions and fallen into darknesss, many others do, scarred and ready to settle into another path their experiences giving them a better understanding of themselves and their place in the society of their Craftworld.
