When was the Gloam-Eyed Queen defeated? | Elden Ring Lore

In this video I attempt to answer the question of when the Gloam-Eyed Queen was defeated. In answering this question I think we can narrow down her identity.

Note: ‪@BlacklistedSoup‬ has brought up a vital piece of evidence in the comments. There is an interview from Miyazaki where he states:
“In the sort of heyday of the Golden Order of The Lands Between there were two Elden Lords, and Godfrey was the first of these.”

So if we take this literally this would suggest that the GEQ had to be defeated still before Godfrey's banishment. So now we would have to situate it somewhere after the war of the giants, attack of Granssax and the crusade but before Godfrey became a tarnished. This of course brings up some interesting questions. Why is Godfrey never associated with the Golden Order and Kenneth Haight is reluctant to address his time as that of the golden order? It might just be a thematic difference, the order was established late in Godfrey's life yet existed for all of Radagon's reign so that's why one is associated it with it and the other is not. Then there is of course a chance that Miyazaki was just simplifying certain concepts for the sake of the interview or wanted to avoid spoilers. It also begs the question if this would come after the crusade but before Godfrey's banishment then how did Messmer know who a tarnished was? Did Miquella tell him or was it a more general term that wouldn't just apply to Godfrey. Sadly I don't believe we have direct evidence for either of these.
