Taken from Wikipedia,
A Claymore who qualified during Teresa's peak, Priscilla was quickly promoted to #2. It was believed she would become stronger than Teresa in time, and she was one of the group of four Claymores sent to execute her following her break with the Organization. Her lack of experience led to her awakening with horrific consequences.
Sadly Priscillia awakened to a Youma.

I somehow thought that Fiesta's female mage looked a bit like Priscillia.
I feel that the
Awakened Guild was somehow related to Claymore, hence I asked one of the members if I could join when I was like in the level 20s. That rude fella who responded with replies containing ***** phrases, which was so immature. I see no point on the usage of F words. Being high level doesn't give you the right to speak in such uncouth manner, hmm very well he might just be some loser in RL, which constitutes to the number of MMO bullies which I believe many have seen & met before.
I'm not talking bad about the guild as a whole, it's just that one of your members have serious in-game attitude problems.
