A World of Steam and Sorcery
A London-based criminal gang. They take their name from that of an urban legend. Or are they the legend themselves? Spring-heeled Jack is a devil of sorts that would terrorize London and was able to bound great distance effortlessly.
Rumor has it that they opt to only use the minimal force necessary to complete a mark. Their motives can be seen as a more noble type of thief. The Robin Hood of this era, or so they see themselves. Preying on Noble, and sometimes the middle-class to service those of more dire needs. Their tendencies are to relieve the more fortunate of some of their extra wealth to pawn to the highest bidder. The profits then go to further the organization and to aid the impoverished.
