The usual apologies, and request for links, if this has been answered before in the forums or in the encyclopedia...
In CT, when you access the Forest Ruins/Sealed Pyramid in 1000 A.D., after giving you whichever treasure you choose, the Nu says:
13,000 years was a long time.
Belthasar, I shall see you shortly...
This presumably means that this is the Nu that you meet in Belthasar's Keeper's Dome in 2300 A.D. Presumably this Nu was already Belthasar's assistant in 12000 B.C., whom Belthasar had programmed in some way and locked in the Sealed Pyramid.
But how could the Nu at this point know that Belthasar would end up in 2300 A.D.? Even given all the forethought and planning that Belthasar is able to do in various other timelines, by all accounts his initial travel to 2300 A.D. was completely accidental and sudden, and I do not get how either he or his Nu could have forseen it. Any thoughts?
