Land of Legends
Rakvel are very large warbeasts created as weapons during the Second Age. Like many such creatures they were not meant to be able to breed in the wild, but they did. They are blind creatures (though with excellent nose and ears) which seem to be little more than razor sharp teeth and claws mated to a body designed for speed and agility. They are highly aggressive and territorial and will hunt not just for food, but for ‘fun’.
Rakvel are, thankfully, solitary hunters and only meet to mate. That said females have been known to eat their mates if they are hungry enough and the same even goes for their own offspring if conditions are bad enough.
