The Nail Father

Lore
The Legends say that the Nailfather was the creator of nails and the ultimate master when it comes to wielding them. All of which was a complete understatement. In truth, the Nail Father was not only the creator of nails, it was said that he even created the material they were made from. His cloak is made of nails hung from a necklace. He bears five nails, and is able to use all nail techniques ever created. Legend has it, he even trained the Nailsage Sly....
