==Inquiry==

In 2300 A.D., the party can visit Belthasar after first arriving. There, he is shown to be working on the Poyozo Dolls, and mentions that the party will eventually have to climb Death Peak:

<pre>OLD MAN: NO!

   You MUST NOT climb Death Peak!

   Wouldn't make it very far, anyway!
   It has to be the right time...
   ...and...THEY...have to show you the
   way!</pre>

How did Belthasar know Crono was going to die, let alone that he'd perish in the Ocean Palace? How did he know that Gaspar would give the party a Time Egg which would be taken to the top of Death Peak? For that matter, how does Janus know Crono is doing to die beforehand? This ability implies that the future is known can be read, which is erroneous; everything about the Chrono series suggests that time is malleable and the future is shaped according to the will of the present. Since there is no predestination, how do they know that Crono will die?
