Of course we want to know your vision, Terry -- silly question.
In the meantime, here's what I've been going with in my games.
Alternative 1) Utha left Kulthea and rests in Chronogenic stasis in case Andraax fails to keep the vigil and K'ta'Viir escape.
Alternative 2) Utha died of old age, happily and with much relief secure in the knowledge that the next generation would keep the eternal vigil. Althans are not immortal, after all, but extend their mortal years with chronogenic stasis and rejuvenation drugs. This has alot to do with why they're so damn hard to heal, and also why they have this sad tendency to go mad -- their minds did not evolve for immortality, and didn't develop methods of handling it the way elves did. I've always thought Savatage's When the Crowds are Gone captured this, which is why I have included it as a duet between Andraax and Ondoval in my work in progress Shadow World: The Musical
