That was a great post Tik and the end there is really insightful. I learn something new everyday and love the perspective.
Why, thankie-sai!
A very interesting theory. Going by this theory we could assume that

Spoiler:
the Crimson King's "true" form still sits at the top of the Tower?
Indeed. O'course, when it says

Spoiler:
top of the Tower, that doesn't mean the top Room of the Tower. Like Brainslinger says, that Room is where God is rumoured to be. In Insomnia the little doctors (long-timers) state that the Kings Random influence probably stops at a certain level:

"...perhaps there is no Random beyond a certain level; we suspect that may be the case, but we have no real way of telling."

That means the Kings true form, Dis, is at least one level/room below the very top Room. Still at the top of the Tower, but not in that last Room where God is rumoured to be.


Even though Dis is still there (he has to be, the Random is a fundemental part of existance) his one chance of escaping and destroying the Tower is now gone by the end of DT7. He will forever be imprisoned there. I find it quite fitting that Dis, the true Crimson King, is forever imprisoned at the top of the Tower whereas Los' the Crimson King becomes trapped on a balcony at the bottom of the Tower. Both manifestations are, by the end of DT7, Tower Pent.
