If I ever manage to convince my group to try this game, I shall craft them a terrifying adversary. An antipenguin of potent skill and remorseless dedication. Throughout the group's journey he will harry, trap and hurt them, an ever present predator who they have no hope of fighting against. When they have suffered grievous losses, been emotional tortured by his flickering presence, they'll finally gather up the strength and will to confront their indomitable foe.
It is only then they will discover the identity of their tormentor. He shall finally speak to them and utter words which shall forever change their lives.
