Yes, well then I don't understand why you ask the question. Take the he Lord of the Rings, the Silmarillion. Everything was predestined by the song of Eru. The Iliad ? Troy was destined to lose, but the Gods wanted to allow a decade of battle... and so forth. It's a myth/fantasy theme.
You were the chosen and so the surviors of the nautiloid crash that you were on were selected to help you on your quest.
We have Shar, Selune, Jergal and Mystra all getting involved, so something important is happening, and mundane things might not matter so much anymore.
Yes, I make this stuff up in my own head. You ask others to explain this to you, and that's what I just did. Do you want an explanation that is not made up in one's head ? Then you'll have to ask a headless one.
To be clear.
What reason have you come up with for why these gods need everyone to have ties to Baldur's Gate?
I never really asked myself this question before it came up in this thread. However, the thing that has been puzzling me from the start was : how and where did Shadowheart obtain the artefact. I was patiently waiting for an explanation before the grand finale, so you can imagine the disappointment when it never go tcleared up..
But maybe one can make it tie in with the origin of all the characters at the time of abduction. Maybe they all gravitated towards the artefact which would then have been located in or near BG. Lae'zel woudln't be traveling on her own. Maybe she was in a party of Gith that were also looking for the artefact when she was snatched up. Astarion and Tav were naturally in the city without link to the artefact and Gale could be visiting Sorcerous Sundries for his own purpose. But, for me this particular coincidence of locale isn't really a thing. The appearance of the artefact in SH's pocket however will always puzzle me.
