Acually as you think of it it makes some sense. A clan of outcasts from other clans can be good plus sense the speculation ,with the market drops as good reason, is a new clan with "new bonus" it makes sense that the bonus can reflect the clan member's knowledge of the clans. So even if you think its a stupid idea -Miria- it can be a strong possibility. Now I wonder what is that bonus.
Or taking the mask idea, maybe the member have struck a devil's deal with their Leader (called Faust or Mephistopheles) who will give them a magical item (mask, fan, sword, etc) that will grant them achieve their heart's desire in return for servitude. Little do they realize that they're losing their very souls/free will/identity in the process. For example, the Luchador was originally a washed-out has been and with his new mask, he's now stronger and a better wrestler than ever. We are in line for another evil clan and that idea could work.
