I actually tink a lot of that works, using the outline of incite emotion for hands of power is genius in my opinion. And tink the other hands of power can work too, though the queens hand of power to suck all the oxygen out of room, would be hard to stat but than again she would plot device rather than pc potential. And most of the other tricks, could be covered under magic,for those who haven't read the books most Sidhe have some minor powers that are leftovers from being gods or being descended from em, i.e. merry has several powers from being descended fertility deities, which all of course relate to sex, sex mad Laurell K Hamiliton strikes again. My only prob is the idea that the magic is sponsered, in merry gentrys world the magic comes from within the fae itself, not from faerie or the courts, but thats just a name issue more than anything else.
I am still having trouble making them fit in dresdens world, at first thought it would be easy but now feel like will have to replace most of what we know bout the fae and the courts from the dresden files, with improvised stuff from the Merry Gentry books. Not an easy task, as still trying to keep the changeling template, altering it so that rather than become npcs automatically if they gain all the powers of their race, rather if refresh allows they upgrade to a Lesser Fae or Sidhe template but still being mortal, like merry, even though the books hint that she may no longer be mortal, and using the sithins as areas that reside both in the mortal world and faerie, the Sidhe Knights remaining, and could even increase as it says in the books that there are humans who have been infused with Fae Magic. The rest, not so easy. As in, how would the white council treat the them, the same as they do fae in dresden files, or since they have free will as sometimes allies/enemies.
