[Disliker of the mary sue]

Hm something I was considering for a game of dnd was playing a cleric of a god of thieves. The process of thinking was I want to play a roguish personalty type character yet I also want to be a cleric so I can actually have a good use, so logically a chaotic neutral god for thieves rouges and bards would have kind of a loose moral rule set so I can be a bit of a rogue while avoiding the problem of the stick up his ass lawful good paladin.

Hm I just wondering how exactly would such a thing be organized with temples and the resources to train clerics to begin with if your main worshipers are traveling mistrals and thieves people who probably can't have a public church. Would worshiping such a being be something you keep to your self or like social stigma? I don't know anyone has any thoughts, are their real life equivalent temples to gods of thieving and debauchery? Figure this be a good place to ask since everyone in this forum seems to have very esoteric knowledge.
