You would know two things: first that the city you lived in did not worship the Bright, nor was it part of the nation that spawned it. That's relivent due to the second thing to know: when word of the Bright was spreading outside if the nation, consuming the whole continent, it wasn't unusual for cults to pop up claiming worship in the name of power and protection.

Most of the gangs you dealt with weren't very religious. Sure some folks swore to a god and some notable members were devout, but they were street gangs, not cults. But you remember this cult, some sort of Bright cult that went about trying to convert people to join them. You never had any direct conflicts with them since they never seemed interested in controlling the city like you did, but they were still everywhere and you do remember that a lot of grubts in your command we're Bright followers, at least before you were betrayed. 

That being said you don't really know the cult or how they operated. They never directly opposed you so they simply weren't on your radar. The symbols are familiar enough, but you're pretty certain your city doesn't have a quiet costal village like this anywhere nearby it.
