The fachan is a roughly humanoid creature that haunts the rugged hills and mountains of Scotland. Its appearance is very striking; it has one leg placed centrally under its body, one arm sprouting from the middle of its chest, and one eye in the middle of its face. It has a single tuft of extremely tough hair rising from the top of its head.
Despite only having one leg, the fachan is both quick and agile and makes a formidable opponent. They prefer to ambush lone travelers on the mountains at night or in foul weather but have been known to attack isolated farmsteads for food.
Combat: The fachan has a strength of 18/50 and gains a +1 attack bonus and +3 damage bonus when using a weapon. An unarmed fachan can tear with its single claw for 1d6 damage. Fachans use melee weapons such as clubs and axes, preferring brute force over subtlety. Their main tactic is a fast surprise attack, seeking to overwhelm the opponent quickly by sheer force.
Habitat/Society: Fachans live in caves and other sheltered places in the wildest and bleakest of hills and mountains. They have also been known to lair in abandoned stone cottages in the mountains, and the temporary huts used by shepherds in upland summer pastures. They are entirely solitary; fachans are only seen together if compelled by some more powerful creature. Nothing is known of their reproductive habits, if any, but they can live indefinitely unless they are killed in combat or by some accident.
Ecology: Fachans eat any form of meat and seem to waylay humans principally for food. They also eat any wild animals that they can overcome by force and surprise. They scavenge from carcasses they find on the mountainside but do not set traps for game. They do not alter their environment at all, apart from littering their lairs with bones and debris and any valuables that their victims may have been carrying.
