man this is factually WRONG the wall of the faithless wasn't created to "punish" those who refused to worship gods, it was created by Myrkul who was the god of the dead after Jergal and its purpose was to not only to force mortals to worship out of fear but to make sure they remember him if he ever got killed, after all gods in dnd don't truly die while there is still someone that remembers them and what better way to claim his place in history than by creating the biggest cosmic abomination against mortals, heck the freaking wall isn't even necessary for Forgotten Realms cosmology it wasn't there originally it was something that Myrkul did out of his overwhelming douchebaggery, the cosmology would still work just fine if the damn wall wasn't there, then the souls of the faithless would most likely go to the outer plane most matching to their beliefs, you know just like EVERY OTHER SETTING OF DND BESIDES EBERRON (that one is another clusterfuck, because there EVERYONE gets the wall of the faithless treatment, Forgotten Realms is the ONLY setting where souls are siphoned to the fugue plane and ONLY because of Myrkul's doing), also the image you are using comes from the game where part of the story is to get RID OF THE FLIPPING WALL and if only Wizards of the Coast weren't such prissy little A-holes to Obsidian back in the day then the ending would have been the utter destruction of the biggest mistake ever added to this setting, the wall is NOT compelling people its bullshit, and the fact that the so called "good gods" of the setting haven't done anything to push for its removal, puts a BIG question mark on whether they are truly good or even actually worthy of worship AT ALL, after all they are condemming people to extreme spiritual torture and being doomed to dissolving into inexistence JUST because they don't want to become their pawns (because that's what mortals are for the gods of Forgotten Realms, mere pawns), the whole thing is nothing more than pure and disgusting spiritual blackmail, and if any of you are actually fine with any of it then there is something wrong with you, i for one want the choice to tell "godly" A-holes where to shove it.
You really need to read the avatar books to get why the wall of the faithless still exists Kelemvor even tried to get rid of it but it backfired on him so Kelemvor had to put back the wall of the faithless he even says in Neverwinter Nights 2 Mask of the Betrayer that if Kelemvor removed the wall again all of the deities would move against him Kelemvor is a powerful deity but he would have no chance of winning a battle with all of the deities that would try to kill him Kelemvor does not want the wall of the faithless but it is a necessary evil because people would stop worshiping deities and deities need worshipers to live without worshipers a deity would die this is why all of the deities want to keep the wall of the faithless around I don't agree with it but it is what it is you could say that before the time of troubles the wall of the faithless was not needed but with Ao new law making that now a deity needs worshipers it is very necessary for the wall of the faithless to exist if you still do not want the wall of the faithless in Forgotten Realms than you need to take it up with Wizards of the Coast they are the ones who made the wall of the faithless cannon in Forgotten Realms
