In TCTC, the events all seem to have some sort of purpose, as though they are meant to happen - from beginning to end, every event is vital to the outcome. Some even seem to suggest that there was no other way events could have occured...
Take LFB - the start, in Lord Foul's message:
The final line says that he will have the command of life and death - and forty years later he gains it - but through events he supposedly had no control over. Think about Covenant's actions from this point - he rapes Lena, and she becomes pregnant. He makes a bargain with the Ranyhyn for one to visit her every year. Lena gives birth, and the Ranyhyn take Elena to their celebration, where she becomes tainted for the rest of her life. She goes to Melenkurion Skyweir, and Covenant decides to help her get in, and as a result, she breaks the Law of Death - if any of these events had been different, Foul would never have gained his 'command of life and death' - but every event was not controlled, it was a result of a choice made by Covenant. The fact that Foul knew what the results of Covenant's actions would be 40 years before the final result was attained suggests he may never have had any control at all.'Say to the Council of Lords, and to High Lord Prothall son of Dwillian, that the uttermost limit of their span of days upon the Land is seven times seven years from the present time. Before the end of those days are numbered, I will have the command of life and death in my hand.'
That example can be put down to Foul's machinations, but there are similar events that work against Foul - Hile Troy. Hile Troy was sent when Covenant was summoned by Atiaran - perhaps this is an act of the Creator to prevent Covenant coming to harm? Anyway - he gains command of the armies, and takes them to Garotting Deep - where he becomes a Forestal. He becomes the Last forestal over time, and in the end it is his actions that save the Land - by allowing the Law of Death to be broken - this seems almost as though his final action was intended - as though he was summoned for the sole purpose of becoming Caer Caveral.
I would go on, and talk about the Staff of Law, but i think I've gone on too much anyway.
It is strange how these events all work to eventually help either Foul or the Land, as though each was predestined to occur as part of some plan for the Land - as though the events were all inevitable, and unavoidable. Perhaps no-one ever had any free will in the Land - all events would occur as they were intended.
