Linear has lived most of his life in Cloak Wood (a little way south of Alsinu). The years in his town have shown him the cruelty of the world and how people have no respect for the soul of the land. Spending most of his time in the woods hunting with his trusty Longsord - Rusty, he finds peace with the fact that all of his kills are to provide for his community and never a piece of fat nor bone is wasted.
Natures Wrath at his disposal, he typically does not force the animals he kills to flee, but instead traps them and topples them with his quarter staff. Killing is not something he does lightly, and often heals small animals with the laying on of hands to ensure only those whom he intends to eat are sacrificed.
Feeling all animals (and even plants and trees) have souls, it is easy to understand why Linnier speaks with animals daily. The ravaged world has torn him away from his home with little but the clothes on his back. But the birds tell him adventure is near, and the salvation of the land is possible only by seeing what is over the horizon. So, he ventures forth.
