Removing the pure blood idea is fine. I dont see a problem there at all. It was just tossed in from copy/paste. Also, betelgeuse, I love the character. Character and positions approved. Though, I warn you about making toooo many characters. You might bog yourself down. Also, I would request that you hold off on making a second adult character until we get some more applications (letting everyone get a chance to get the positions they desire). 

Lastly, Potato, I have no problem with you making somewhat of an evil character. I indeed have a villain planned, but personal sub-plots are okay as long as they aren't toooo big.
