The Codex 26: They will have their prophet

I have the answer now. I know the truth. I shall not touch that wretched thing again. Best that no one do, now or ever. I have tried – at last – to destroy it, but it will neither bend nor break nor melt. Oh the irony – I am certain if I asked, the Apple would tell me what need be done. But even this promise is insufficient. Always it holds one more gift to give. I must refrain. So it shall be sealed. We will take it to the island – once theirs, now ours. There is a treasury there – hidden well – and it shall have to suffice. Risky to separate myself from the artifact that others may discover it. Riskier still to keep it close. In time I will be tempted. I am weak. We all are. Who wouldn't be? Oh, the things I have seen... The tale is here – inside the text. Not between the lines but beneath them. Where only our eyes might peer. Go and see it for yourself. That you might succeed where I and the others have failed. Time marches on – bringing with it new discoveries and developments. And so at least one day the doorway might be opened and the message delivered. They will have their prophet.

Commentary: Mario Auditore saw something behind these pages. "A reference to two pieces of Eden" though nothing about two pieces of Eden appears in the Codex. This implies two things:
1. What we see of the Codex may just be the tip of the ice berg.
2. Mario may have had some of the Eagle Vision. Which makes sense, given his lineage.
Altair mentions here that he sealed the Apple away in Cyprus. He had tried to destroy it but it would not break. It could have easily been buried or dropped into the ocean. But even then, I would wonder. Would it somehow find a way to resurface? Does it float? Even then, It may have some means of defending itself, should someone try to dispose of it. 
"Temptation incarnate" that was how Al Mualim described the piece of Eden. It has the power to change the world; to give an unlimited amount of knowledge and command the minds of men. One has to wonder, if one was offered this device would one so easily refuse?
Personally, I do have some small hope for humanity. That they do not need to be controlled. That it is better to create a world of peace through people's own realisation of the truth. But sometimes when I see the ignorance of some people and the sheer malice of others, I do wonder.
