Trying to build a town, helps appreciated

I am going to eventually hold a game in a year time lol but for now as a beginner I am setting things up. The campaign will continue the story from where Baldur's Gate 3 ends.

But the town I am building is set in much earlier than this. In fact it is meant to take place at least 7-9 years before Descent into Avernus. So it takes place in Faerûn.

Here are my plans:

1. I'd prefer the town to be somewhat quaint and a bit boring even. A few places of gathering exists that aren't the usual taverns but more eateries.
2. The weather conditions are rather far apart with really hot 27-30 C during the day to 3-5 C at night, while being rather windy. But not a desert. It's green more than less. And this is the average "summer" weather lol.
3. The town worships Kelemvor, Pelor and a very very VERY subtle feel of Raven Queen. But I need help with the last one.
4. I'd like the town to not be that well known in the sense it is so in the middle of nowhere, people knows more the more active/bigger places.
5. I want this town to have somewhat of an on again/off again issue with undead, hence those gods. No one really trades that much with this town, rather this town mostly has traders who goes out to maintain economy.
6. I want this town to have some of the more downtrodden races. Tieflings, Drow, Deep Gnomes, etc.

Now my question is:

• is this all possible?
• I am keeping Raven Queen really subtle because idk how much ppl of Faerûn would know her but on google search I see a lot of people recommend her for "gods against undead". But i wanna keep the "is she a goddess? Is she an entity?" mystery heavily active. So how known can she be?
• As shown in the image, I'd prefer the town to be in the "DARK" whatever that is in the upper right corner. Close to forests so there can be abandoned old crypts and graves that is where the undeads come from.

Thank you all in advance for the help!
