I am currently juggling ideas for my character, but I have a generic idea for my witch family. Posting it here just so others have some clue to what I'm thinking of doing:

I am planning to have a family (we'll just call it family X for now) that is proficient in the school of alchemy and [url= http://powerlisting.wikia.com/wiki/Symbol_Magic]symbol magic[/url]. Family X is actually a branch family that originally was part of a larger family (family Y), which was gifted with astrological divination and other star related/effected magic. However, since the disappearance of the stars, their star related magic became practically useless and the family divided into independent houses with their own leaders and their own specialty (if anyone would like to be another branch family, you are welcome to; your witch family would simply have a common ancestor with family X and nothing more). Whether it's related to family Y having star related magic or not, no one knows, but ever since the disappearance of the stars, the decedents of family X are becoming less prone to magic; with each coming Emergence, fewer children become witches. Not all of family X's witches can even execute the simplest forms of magic. The only reason(s) family X retains its dignity within the witch community is the fact that their magical items are considered to be of the best quality and are highly valued… Not to mention their symbol magic is not to be trifled with.
