Thousand Cuts

"Mordret, Mordret… you remained pretty passive in the Second Nightmare, didn't you? The only time you shared your knowledge of the future with me… was to tell me that he couldn't be allowed to enter the Ivory Tower."

Sunny hesitated for a moment, then smiled crookedly:

"But then, what you really wanted to achieve was not preventing him from entering the Ivory Tower, was it? It was making sure that he entered the Ebony Tower instead, and collected whatever it was that Nether had left there. By telling me that one sentence, you achieved exactly that."

He felt as if the ground was disappearing from beneath his feet. 

What had happened to Mordret in the Ebony Tower? The Prince of Nothing had not shared that information completely, but he did mention that after leaving it, he was much harder to find with the help of divination. The strange, vague symbols Sunny had seen on Mordret's soul core were the result of that.
