Re: your seating chart: Don't forget that Cyndane would be very offended that she wasn't invited, since she was Very Important to Lews Therin and Rand.
Okay but Cyndane probably should get an invitation if ‘mindtrap held by’ counts as an edge on the familial-or-mental-bond relationship graph. Which means Moghedien should be there as well, but more interestingly it brings up the question: should the Eelfinn be invited?
Alternatively, we could say that all of the Chosen should be there because: Moridin has an invite due to being in Rand’s head, and like the other Chosen he is effectively soul-sworn to Shai’tan, which I think could count as an adoptive familial relationship of sorts, which means Shai’tan has an invite, and therefore his whole ‘family’ does as well.
At which point you may as well just extend an invitation to the Creator, too, because ‘personifications of opposing metaphysical forces driving the universe’ sure sounds like immediate family to me!
(if anyone is incredibly confused at this point, context is in the first full paragraph here)
