Were you around in the late 90s-early 2000s? Because let me tell you that the prequels did not spark joy for people then. It was insane the amount of hate leveled at Ep 1-3. Hell kids at Jake Lloyd’s school bullied him so hard he quit acting.
So you never know, 7-9 might spark joy for people in 20 years.
The sun isn’t big enough to go nova, period. It will swell up in ~5 billion years when it runs out of hydrogen in the core and starts burning helium. Then the sun will start climbing the fusion chain up to iron and there the fusion reaction in the core will die out. When this occurs the outer shell will kind of just slough away leaving a planetary nebula and an extremely hot naked mostly iron core. This core is a white dwarf and will just continue to glow for a few tens of billions of years until it loses all its heat. No fusion is happening in this bad boy it just glows from the residual heat and the heat is so hot it takes longer than the current age of the universe for that heat to dissipate.
Back to the original point though is that the sun won’t explode in a supernova because it lacks the mass to do that. You need a star that is at least 8 times as massive as the sun in order to get a supernova.
Do you have karmic dice on? On the lowest difficulty with karmic dice the enemies tend to hit and crit more often since they get the same +hit you do. Turning that setting off will make your rolls more random which means you can have good and bad streaks but the enemies are less likely to crit you every other hit.
How did you enter the church? You can sneak in the right hand side and avoid two of the fights. You only have to fight the skeletons (which you can disarm).
Also you can talk your way out of the first fight at the church. Or you can kill half the guys there by shooting the giant block hanging over their heads.
Don’t be scared of combat, just use quicksave liberally until you feel more confident. There is almost always a shortcut or easy way out of combat in BG3. My current run i’m trying to solo tactician so you gotta skip as much as you can. I’m at several hundred hours in the game so if you have more specific questions don’t hesitate to ask.
Make her a vengeance paladin. She’ll hit like a truck and can still heal. Also thematically she’ll still have the sharran choices as she is identified as a paladin of shar (the only one in the game).
One thing I remembered that is similar to your question about using the white dragonborn for dialogue. If you leave the dark urge’s name as The Dark Urge there are a few lines where the narrator will say “You say your name, The Dark Urge, out loud” instead of “You say your name out loud” if you have a custom name. The first instance is when you awake on the beach after the intro scene. There might be more but I can’t remember off the top of my head.
