The "female Bandit leader" is a noble that tries to innitiate a rebellion against the current Baron of the Area weirdwood is part of. (taken from the letter found in the hideout)
Her Plans for that should have received a bit of a set back with the death of her ally and the defeat of the Banditgang...
The letter indicated that she wanted to reduce tension in the settlements of the area in order to get in power herself... with the Goblingang supporting Weirdwood and it's mayor, the revival of 2 opposing Religions in the Area and the unknown factor that is the MC she might be intrigued enough to personally visit... and maybe attempt to seduce the MC in order to make him her new minion.
Also Fast Travel will likely get more important with a bigger Worldmap... the only Problem with the short times you need to spend with the girls is the sheer ammount, at some point you'll have to many lovers to stay in their good grace
