I reckon that the Seanchan prophecy of Rand kneeling before the Crystal Throne has already happened: namely in the great vomit scene in Ebou Dar when he falls to his knees after attempting to channel.

I believe that the original prophecy discussed this as Rand kneeling before the seat of the Seanchan's power - which, after the destruction of the Imperial Family is no longer on the seanchan mainland, but rather where the main forces and Empress are gathered: Ebou Dar. It doesn't actually reference the chair itself, nor indicate Rand surrendering to Fortuona in any way.

This is an importantstep to him discovering tears and laughter, it's the moment he sees what he has become. Without this scene, would we have the revelation at the peak of Dragonmount?

Ishmael managed to corrupt this section of the prophecy to make the Seanchan belive that they would control the DR. We've been told by RJ that these prophecies are corrupted, but haven't really seen much of an indication of how.

Could this be it?
