I have just asked a question relating to Mordenkainen, and this answer refers to a fan theory which I found really interesting. I would be very interested to see if there are any other similar theories, but I am pretty sure that asking for them would be opinion based or too broad.
I think this is the right place to ask if anyone can help me find a stackable way to ask about these theories? I can go to the various forum sites if I have to, but prefer to try and avoid it.
The related questions suggest rewording to a problem, but I am not actually sure how I can do that, so will explain what I am looking for:
I am doing research for a character background, he is a wizard, background of sage:researcher, and through his research has come up with a conspiracy theory that many large events throughout history have been manipulated by persons or groups unknown.
The original idea what that it could have been done for the personal gain of this group, but upon seeing Mordenkainens background I figured he was a good figure to have as the target of my theory, that my character was seeing the threads he was pulling but not knowing who was pulling them (he doesn't exist in my setting, so the DM would be free to put the blame on anyone, or make me wrong).
After seeing the fan theory it looks like part of what I am looking for is 'events that never happened', in the case of this particular answer a peace treaty that never happened.
I suspect that there will be other events that never happened, but since the significance of these events is unlikely to ever be compounded upon in lore I suspect it will all be theorising by fans.
I could ask for the history of wars in a particular setting, including wars that brewed but didn't spill over into full scale wars; or peace treaties, including those that never got signed; but asking a specific question about each type of string relies on me knowing what type of strings have been pulled beforehand.
