Sam walked to the Silva temple and wanted to crack the code of the temple too.
But while he was doing so, several thoughts are eating his mind.
It is easy to crack the code, once they identify the similarities between the two temples. And Sam is not narcissistic enough to think that he is the only guy who managed to guess the purpose of the similarities in tens of centuries.
But that raises the question, why it was not opened until now?
Sam doesn't know, but he wants to know that. As for how to know that, the only way he could think of for now is to try and open other temples and see if he could find any plaques similar to the one that was in the Rata temple.
It also stated that the path wouldn't open for feathered. Sam would like to know the reason and find the whole story so that he could think of ways to utilize it to his own benefit.
