I know about Minthara, and she makes sense, not that I would normally go down that path. And I don't think any one would make into leadership at least in the enterprises I work for with her persona, but who knows what's under the hood.
Well yes. Because she is a drow, and this is the setting of Forgoten Realm, it is normal for her to be that way. And Laezel is Gityanka, from the same setting. This is also her nature. Any comparisons to real life are silly.
You romance Shadow Heart, so don't worry
