Waywatchers

Waywatchers are silent sentinels, the guardians of the paths leading into Athel Loren. They are masters of concealment, and can lie unmoving and unnoticed for days on end before springing an ambush on a startled and unfortunate prey.

Most commonly, the way of the watcher is the natural progression for those who have trained as scouts, though more rarely, unblooded youths can feel the call of the forest coursing through their blood. Over time, an Elf may find that he is more comfortable in the forest’s embrace than in the presence of his kin. He will drift further from the halls, spending more and more time in the forest, honing skills of stealth and marksmanship. Many never return from this journey, for there are corners of Athel Loren that are dangerous even to the Elves, yet those who survive are skilled beyond compare and hardened by their experiences.

Few warriors can match a Waywatcher’s skill with a bow. Should they wish it, these silent stalkers can loose an unerring stream of black-shafted arrows in a heartbeat, or place a single shot precisely in the weak point of a foe’s armour. Furthermore, Waywatchers are highly adept at the arts of disruption and surprise, often appearing silently next to a vulnerable enemy and vanishing as quickly before the body even hits the ground. Thus do any who enter Athel Loren run the risk of being slain without warning by the Waywatchers, cut down by unseen archers or falling prey to their cunningly constructed traps.

Waystalkers
Waystalkers’ personalities have become entirely submerged by their obsession with stalking prey. They are taciturn and solitary individuals, and they may let years pass between visits to Wood Elf halls. Waystalkers are perfectly at ease within their forest homeland and effortlessly survive by their wits and cunning in the wilds. On the rare occasions when a Waystalker returns to the halls, he stands apart from all others, for he is closer to the forest than to other Elves.

A Waystalker’s marksmanship shames even that of other Waywatchers. H e can pick out a single enemy from a seething mass of troops and place the one perfect shot that brings the target, lifeless, to the ground. "Set the Waystalker finds no reason to exult in the application of his skills — after all, what prey could hope to escape one who has dedicated his entire life to the hunter’s art?
