So our opening is excellent. We have a condition, and we find ourselves in the middle of nowhere with nothing on our side but an unlikely alliance.
--I do have a small issue with how this is done. If we were knocked out of the side of the ship, how is it that we wake up right beside the ship? Wouldn't the ship be a lot farther away after having crashed? Or did it drop straight down beside us?
--That's an example of what we would call "refrigerator logic." The idea being that the logical inconsistency doesn't generally occur to us until later. Regardless, it's not the biggest deal because the essence of what's happened is clear. Personally, I would prefer that we just crashed with the ship and were thrown from it onto the beach, but if Larian feels like there's something important with the fall and the magic keeping us from splitting our heads open, fine, I can accept that without screaming about bad writing.
The opening/religious setting is basically 1:1 DOS2 - your ship is attacked, you drown/fall to death and some god seems to intervene and save you. Then you have a religious cult that is trying to take over/save the world.
Reusing that opening and setting is not necessarily bad, but a little bit lazy.
