I haven't read all 8 pages, so sorry if I missed something crucial.
The world building starts with the question "What does Tav allready know when dropped from the ship." and then how to convey the most important bits to the player so the player is up to speed with what the character is supposed to know.
I agree with the OP in the sence that it feels like you are playing someone with total amnesia (and yets also not).
Digging round on youtube it appears that the city of elturel has been to hell and back, and that the refugees are an effect ofElturel having returned from hell/Avernus.
Stuff like that might be told in one fashion or another.
I also miss something I miss in the opening cinematic: a first person shot of running in that city (which was it actually) and getting nabbed: it's lacking that moment where you go from the world building exposition to zooming in on the protagonist afolling him/her. it just jumps from exposition to the character creator.
