I've just introduced a new sword into my game using the legend of the 4th nail. I've called it Pietacchius, the Sword of Piety. In the lore of my world, each of the swords is associated with an archangel and this one is associated with Uriel, which is also why I've been calling it the hidden blade. It is only made available when things are truly dire. In my version of Austin, Uriel has tasked the player with guarding a newly minted Ley Node that that was created when a skinwalker shaman attempted to reawaken the spirit of the Earth. I'm treating it like the Buffy Hellmouth in Sunny Vale, it's a slowly expanding node of magical power not associated with any ley lines and now all of the supernatural world wants control of it and are heading to Austin.

Since in the Dresden lore each of the wielders of a sword is descended from nobility, the wielder in my game is a descendant of the first Gypsy who kept the 4th nail, thus making the fourth nail possible. 

There's a thread around here somewhere concerning the Legend of the 4th Nail. I'll see if I can dig it up, but I'm introducing the 4th sword in my game as the Sword of Piety.

Everybody seems to focus on spells that don't violate the laws. I personally like to think about spells that would break the laws, to give the villains (and some PCs with a more evil bent and refresh to spare) cool things to do that are plausible in the rules. A lot of the actual Law breaking seems to be done through thaumaturgy, but I don't think that the 1st Law should be the only one possible to break through Evocation.

The 3rd and 4th law seem easy enough to break through Spirit Evocations. What about the rest though?

I would do it as a block using the weapons skill.

I just thought it would be a fun way to keep Bigfoot in the world. It would explain why people keep seeing them, but why no large populations exist to be found (because they shape shift into other animals). I also went back to old stories how they have attacked logging equipment and what not to give them their current motivations.

Been toying around with this idea for a while.

Since the dawn of human memory, the Naagloshii have existed as part of our world as messengers between the Holy People and the different mortal clans of North America. Semi-divine immortals, their power was bestowed on them by the Holy People as they were entrusted with protecting the natural world and teaching the clans the skills they needed to survive. It was understood that this power was temporary. When the Holy People were about to leave this world, they called back the Naagloshii. Most came, but some did not. Those that remained had become selfish with their power and refused to return it. They hid from the Holy People. Since that time, any Naagloshii encountered were not like those the first people knew. They were sadistic and cruel, exemplifying the harsher aspects of nature. They began to hunt the first people for food and tortured them for pleasure. They even took some mortals for the purpose of breeding. Thus the first Stiyaha were born.

With traits of both parents, the Stiyaha are described as large hairy ape-like creatures, standing nearly 10 feet fall and weighing 500 pounds, covered in hair that ranges from dark brown to golden. They also gained the Naagloshii's ability to transform into different animal forms. They can be faster than the fastest deer, stronger than the largest bear, and more agile than the nimble hare. The first people have always known of the Stiyaha, calling them such names as Kwi-kwiyai, Skoocooms, Sésquac, or Ts'emekewes. In modern times they are known by their anglicized names: Bigfoot, Sasquatch, and the Yeti (for those Stiyaha that fled across the land bridge that connected North America to Asia). Each tribe had a different relationship with the Stiyaha and their creators. Those that chose to follow the Holy Path found their presence reviling. There were others still that attempted to emulate the demons and their progeny. These truly mortal practitioners became the Skinwalkers of legend, evil shamans that have learned to wear the skins of animals and emulate their gifts.

While the Naagloshii want to learn to harness other gifts like those taught to them by the Holy People (usually by feeding on the power of the being), the Stiyaha are most interested in returning the world to it's natural primitive state.

Wyvern described how I'd do it. Mess around with the text of Beast Change until you get something that works. Basically it's just a way to change around the skills since the entity inside the head couldn't really affect the outside world and all of it would be story driven by the player. It also gives a great reason for having Sponsored Magic (Crazy Internal Head Wizard). Maybe even an Involuntary Change that could be like having a second character sometimes.

Man, I'd love to see the aspects for that.
