The Wall is also tied to one of Mrykul's Get Back from being Dead schemes in the best sort of way
Basically he gets to be a completely evil jerk, because no one is really going to argue about him taking souls that don't believe in gods and shoving them in a wall to suffer for all eternity. There's... A big ol' thread going on at the moment about it and its current existence, but there's no questioning why Mrykul made it in the first place
Whenever it really comes to the Wall and its existence, the best source I can recommend is Neverwinter Nights 2, Mask of the Betrayer. Its no Planescape: Torment, but its close
