She considers. Currently she is in an awkward arrangement, working out of the city's only temple to Shelyn. It's in the Ivy District, on the edge of Ivy District Park. It's a quarter mostly inhabited by the nobility. It's safe. Her apartment is in the Coins, but a relatively good district of it. Her old place of work was there too, and relatively good as well; her madam kept the guards close with coin and that solved many of the issues that most working girls in the city face daily.
Alright, let's go district by district.
Ascendant Court. It is the obvious place; all the major cults and temples are there because everyone who tries for the Starstone goes there. It is loud, bustling, full of pilgrims. A wonderful place to trap the ecclesiastically unwary. She's going to stay well away from it at all times. The last thing she needs is to attract the attention of some sixth-circle wizard who feels personally affronted by her presence.
The Precipice Quarter. It surely needs her ministrations. Entrance is also completely banned, and for good reason. The area is cursed in an entirely non-metaphorical way. She could try it, but she would likely die to no good end. Perhaps when she is stronger. Much stronger. It can also be struck.
The Ivy District. It's beautiful, it really is, built as it is around its park and Shelyn's temple - but it's too good, too already-cultivated. It's full of nobles and full of art and doesn't need her.
The Petal District. Far, far, far too expensive for her. She'd never afford the rent. It can also be struck. The Wise Quarter has the same problem.
Eastgate. It's a good neighbourhood, a safe place to grow. Gentle. She wished one day she'd move there. But Rose's apartment in the Coins is good enough for her. She could afford a more comfortable life, but... For now, she doesn't need it. And so too should she not put her shrine here. It isn't needed, just like in the Ivy District.
Westgate. Very traditional, and could potentially use her help. But she doesn't want to be a piece in the gates' rivalry, and she would inevitably become so. It's also a little like the Ivy District in that it doesn't need her help.
The Foreign Quarter. If she wishes to tend primarily to the Nidalese residents of the city, this is a good choice. However, there is a distinct aura of Cheliaxian influence in some quarters, which is a definite drawback. It has a greater variety of simple joys than anywhere else in the city. She should consider it carefully.
The Puddles. It's sinking, it's soggy, it's diseased, it needs help. The streets are flooded for half the day and it's slowly starting to die. There's rumors of goblins and a cult of Norgorber. It desperately needs her, but she doesn't have the skills. Even with all her people at her back, she's unlikely to be able to heal it. Is it worth it...?
That leaves her best two candidates for last - the Coins and the Docks. The Coins has Mudhaven, which needs the help, and it's full of businesses of various legalities. There are fewer brothels than on the docks, but still many, and the sheer variety of mercantile services on offer is enough to make a temple of a pleasure goddess able to acquire almost anything they need. Unfortunately, guard presence is... Token, at best. She'll need protection if she's going to operate here, or else to own nothing worth stealing. It does have the advantage that she grew up here and knows it better than anywhere else.
The Docks are similar, full of sailors and travellers. The guard presence is better, though. There are plenty of gangs in the darker corners, including one that plays for Cheliax, and she'd have support from the Firebrands. It's also the section of the city with the most whorehouses and taverns per yard.
It seems to her that the decision is between the Foreign Quarter, the Coins, and the Docks, with a potential chance for the Puddles.
