music behind the following scene

WEI BOYANG
You know this because you have traveled that far into the future.

DR SAGE
Further actually. I have been able to push the boundaries roughly 2300
years in either direction.

WEI BOYANG
The things you must have seen!

PROF SAVANT
Yes, but she is not going to tell you of them, are you Petronella?

DR SAGE
Erasmus is right. This conversation has already broken our rules. Mx
Entwhistle would be very angry with me. I am afraid you shall have to
learn of the future as it comes to you, Master.

WEI BOYANG
If you do not provide me with enough details to arrive at the
right moment...

DR SAGE
...but you already have, because that happened in my past. I am
confident you will solve that mystery.
