Help! I saw the prophet guy preach but never followed the guy who talked to me afterwards, is there any global variable I can change so I can resee these events and do the quest? Or is there any way to reset the temple district?

How about walking into the temple of helm and temple of lathander instead of starting to mess with CLUA? In my experience the one you need to talk to is always in one of those temples

After you see the little cutscene, a priest from either the temple of Lathander (if you're a good aligned cleric) or helm (if you're not a cleric or a neutral one). iirc, if your protagonist is an evil cleric, Talos approaches you. Anyway, once you talk with them, you can look in the sewers under the temple district. That is the proper way to do this quest.

If he broke the scene with CTRL+J where cleric walks away, he won't be able to get the quest. In such cases: reload. And avoid CTRL+J.

I dun have the console activated normally unless I encounter a bug or a missing npc, but it doesn't matter I've found the global that changes this its BEHOLDERPLOT 1 just in case anyone else has this problem
