Thank you... as you can see, I appreciated the efforts and decided to reply
I've read the various posts on the topic of TC and Berek being one, as well as that part of SRD's interview regarding TC becoming Foul by the end of the Last Chronicles... Here's what I think on the topics.
That TC be truly Berek sounds to me a little too easy... in that, as we can easily see, it's what almost everybody expects, and we all know that SRD doesn't really go for the obvious most of the times
But supposing that is what will happen, a few thoughts that come to my mind are:
1) The legend of Berek is truly old in the Land, and as such, it's unlikely it was passed on faithfully from generation to generation, especially during the years following the Desecration; certain things might have changed in the telling, or outright removed, we can't know about that. To make an example: someone theorized that if TC were Berek, then he would eventually fall in love with the Queen, side with her against the evil King, and so on - but where does Linden enter the equation? Is the old story truly accurate? What if Linden were the Queen herself? How could TC/Berek use a Staff of Law if he is outside the Law ( as he himself recognizes by the end of the First Chronicles - and interestingly enough, using the Staff of Law is something Foul can't do either )? Who is the evil King? Although I must admit that the growing similarities between TC and Berek are intriguing events - even his being titled EarthFriend by the end of the Second Chronicles, the same title Berek bore.
Another question: is it just me, or do the differences between Berek and Foul appear to make them strikingly complementary? A far-fetched theory: could Covenant be somehow both, or rather, could each of them be an aspect of Covenant incarnated? Berek the Land-lover, the seer, the prophet, the hero, the saviour - and Foul the despiser, the destroyer, the Gray Slayer, the bringer of doom. I would not trust characters who SRD depicts in such stark blacks and whites - especially since the psychology of his characters is far too developed to craft such two-dimensional beings.
Also, even if we suppose Berek is TC, someone said he could change the world, avoiding Kevin's Desecration and all the evil that comes before and after; but that above all he could NOT do, because if he did it, he would create a terrible paradox. After all, if he passes on all he knows about the later Ages, if the Desecration doesn't occur, then the line of the Old Lords wouldn't be broken, and the Lords of the Land would have mastered all of Kevin's Lore, and would have never lost the Staff of Law, which would therefore have made it impossible and needless for Covenant to be summoned by Drool in the Land's time of need, therefore undoing what we know, and above all, making it impossible and useless for Covenant to go back in time and turn into Berek, thus undoing what we just described - a confusing statement to explain how TC being Berek and changing things would cause the breaking of the Law of Time.
So: if TC goes back in time and becomes Berek, then he would be unable to change anything that he knows will happen. But would he psychologically endure a life knowing that all he builds will be brought down by his great-grandson Kevin? And would his impersonating Berek be enough to undo Time's corruption?
As for the theory about Berek being alive in our world: that theory holds some fascination, in that it isn't contradicted by anything we know of Berek and his final years. The fact that the singer retracts having called for Berek, before TC's third summoning, might just be seen as protective instinct: if you knew a Berek and you mistakenly were to call someone by that name, and then that someone later comes to you and feverishly asks you why you called him Berek, wouldn't you deny it as well, not knowing what this strange and possibly dangerous man could do to your friend?
Apart from that, isn't it curious that nobody knows what happened to any of the Old Lords once they died? We know they died - but we don't know whether they were cremated, buried, or for all we know, simply dissolved into sunlight. But if they were buried, as it appeared to be the later custom for the Lords - then shouldn't Berek Earthfriend's tomb be a place of reverence and respect? Why isn't it? Why do we not know what happened to Berek when he died, or even IF he died? That's something interesting to ponder, I think.
I'll stop here, or I'll really write too much... let's see what are your comments on my theories
