TWIST ENDING: There is no time travel in EQ. The palace simply moves in place--vibrates, if you will--at such speed that it goes arse-over-tit into its own singularity. Time within slows as a relativistic effect compared to the outside. Eventually, it returns to normality and the "time travel" is complete. It can be seen to travel into the past because time in EQ loops, as in amerindian storytelling traditions and time-conception. That's my theory and I'm sticking to it until it is soundly refuted!
