hmm.... A for hire group that takes care of people's problems, for example a local gang wants to destroy their rivals, Fault would be hired to do this but instead of using brute force they set up small unrelated incidents that ultimately lead to the groups demise. It would look like bad luck or internal issues tore the gang apart. The group is divided into a hierarchy of a sort, at the bottom are extras (they follow the orders of the maestros), above them are the gatherers (they collect information about jobs among other things and find people who need Fault's 'assistance'), the Maestros are the planners (there are about 6 to 8 of them and they make the magic happen), Aisyle himself does whatever he wants.

Aisyle got kidnapped..... *defiant glare* this won't last long so enjoy it while you can...
