This. Madness and mantling aren't mutually exclusive. In fact, given the case at hand, they're pretty mutually inclusive.
You know, while in the shower I began to think about what I said earlier, about how the CoC is standing over the CoC, laughing at his madness. Then it hit me. This could actually be extremely plausible, think about it for a second.
Before we enter the SI, we see that dark elf, gripping his head, looking as though his head was literally about to pop, and kept screaming "nothing is right." Well, how is it that when we enter SI, nothing really look all that off, other than some of the people there. So then I thought, "Well, this place doesn't seem that bad. It's practically Morrowind." Then I began to think about the two halves of SI. Then I began to notice, despite being obvious, that there is a theme with SI; everything is two sides of the same coin. If that's the case and a theme of SI, I began to wonder if there's a chance the CoC split in two. You have the CoC the mortal, and CoC the god. Both are the same, yet different. One is Sheogorath, and the other thinks (s)he is Sheogorath. You mantled Sheogorath, and became Sheogorath. Because of that, you have now always been Sheogorath. If that's the case, maybe SI is not just a reflection of Sheogorath, but is actually you all along. You have always been Sheogorath, even though you have also been mortal all along. And in a realm that is not supposed to make sense, s about complete and utter insanity, improbability, madness, irrationality, illogical events and practices, and so on, it can be seen as being very likely that what I have been saying is completely true.
You are mortal. You are Sheogorath. You are both completely different. You are both completely the same.
Comments, questions, cheese for everyone? Or am I under the sway of Sheogorath at this moment?
