According to the novel “Prince of Lies”, the Wall was built by the Circle of Greater Powers when Myrkul reigned in the City of Strife. There was no Wall when Netheril was destroyed. I was speaking of the Netherese who perished in THE HERALD.
The destruction of Netheril took a long time, depending on who's POV you're using (the Low Netherese tend to date it from when the first arcanists started acting like they were better than everyone else).#Realmslore— Ed Greenwood (@TheEdVerse) December 21, 2019
Though they worshiped Shar. I mean, the Netherese who perished in the Herald. Yes, but Shar led them to their destruction deliberately, and abandoned them/turned her back on them at the end. Hence the Wall as their fate; she spurned them, and straight-out told the Princes why: that they tried to use her for gain rather than being loyal to her.#Realmslore

And this is how Shar ultimately treats all mortals who venerate her, because of who She is: the goddess of (among other things) darkness and loss, the Bringer of Chaos.#Realmslore
