I'm in! I assume there are probably a lot of different "factions" both in and out of super-life, right? Does the city have an official "hero" team? Are there gangs being lead by supervillains or use supervillains as hired muscle? Up-and-comers who need to decide where they belong and if they should even join a team? Be interesting to see gangs and heroic teams alike trying to poach new heroes off the streets. 

[i]Sigh[/i]. Don't feel pressured to answer all of that, I'm just spitballing. Moral grayness in superhero stories is something that sets me off, so I'm eager to see this develop! 

In terms of characters, I was thinking a young hero with newly "awakened" (however you decide to handle the process) abilities on their first few days at being an independent hero. Power-wise, how does "dust manipulation" sound? An ability to control tiny particulate like sand, snow, dirt, etc. (within a reasonable range, of course)
