The characters in the campaign I’m currently running are very liberal and open-minded when it comes to non-human races. They even try to give non-humans that are typically viewed as evil (e.g. orcs) the benefit of the doubt. (At least at first. If the orcs attack, their lives are ended quickly). Naturally, the current story arc takes place in a city where non-humans are viewed as second second-class citizens and sometimes even bought and sold as slaves. I would like to present this mindset as normal in this particular city, in a way that the characters will have to begrudgingly accept it, because they cannot go up against everybody in the entire city.
But this city will also have its own morally ambiguous rebel group. Their goals are freedom and equality for everyone, but they think that the end justifies the means. So they are more like a left-wing terrorist group. There will be assassinations, kidnapped children, the whole nine yards. Now I need some kind of deity (or other figure) these rebels can rally behind. It’s easier to justify yourself when you do stuff in the name of a god.
But I’m not sure which deity would be appropriate. I looked at some domains, like Balance, Change, Chaos, Community, Freedom, Hope, Protection, Retribution, Strife and Vengeance, but none of those deities fit my needs perfectly. Currently, my top two contenders are Tymora and Ilmater, but I'm not fully satisfied with them.
So my question is: Which deity would best fit a morally ambiguous rebel group fighting for freedom and equality in their home city?
The continent where this campaign takes place is a hodgepodge of several areas from different campaign settings, but the world as a whole features the Faerûnian pantheon. So everything within the lore of the Forgotten Realms setting is fair game. I’m not married to the idea that it has to be a deity at all costs, so other comparable entities would be fine as well.
